1 But the Spirit says expressly that in later times some will fall away from the faith, paying attention to seducing spirits and doctrines of demons,
1 But the Spirit says clearly that in later times some will be turned away from the faith, giving their minds to spirits of deceit, and the teachings of evil spirits,
This know also, that in the last days perilous times shall come. For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good, Traitors, heady, highminded, lovers of pleasures more than lovers of God; Having a form of godliness, but denying the power thereof: from such turn away. For of this sort are they which creep into houses, and lead captive silly women laden with sins, led away with divers lusts, Ever learning, and never able to come to the knowledge of the truth. Now as Jannes and Jambres withstood Moses, so do these also resist the truth: men of corrupt minds, reprobate concerning the faith. But they shall proceed no further: for their folly shall be manifest unto all men, as their's also was.
Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. Remember ye not, that, when I was yet with you, I told you these things? And now ye know what withholdeth that he might be revealed in his time. For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: Even him, whose coming is after the working of Satan with all power and signs and lying wonders, And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. And for this cause God shall send them strong delusion, that they should believe a lie: That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ. And no marvel; for Satan himself is transformed into an angel of light. Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit. And there came out of the smoke locusts upon the earth: and unto them was given power, as the scorpions of the earth have power. And it was commanded them that they should not hurt the grass of the earth, neither any green thing, neither any tree; but only those men which have not the seal of God in their foreheads. And to them it was given that they should not kill them, but that they should be tormented five months: and their torment was as the torment of a scorpion, when he striketh a man. And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them. And the shapes of the locusts were like unto horses prepared unto battle; and on their heads were as it were crowns like gold, and their faces were as the faces of men. And they had hair as the hair of women, and their teeth were as the teeth of lions. And they had breastplates, as it were breastplates of iron; and the sound of their wings was as the sound of chariots of many horses running to battle. And they had tails like unto scorpions, and there were stings in their tails: and their power was to hurt men five months. And they had a king over them, which is the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon.
And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years, And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die. And the serpent said unto the woman, Ye shall not surely die: For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
And the LORD said unto him, Wherewith? And he said, I will go forth, and I will be a lying spirit in the mouth of all his prophets. And he said, Thou shalt persuade him, and prevail also: go forth, and do so. Now therefore, behold, the LORD hath put a lying spirit in the mouth of all these thy prophets, and the LORD hath spoken evil concerning thee.
And the LORD said, Who shall entice Ahab king of Israel, that he may go up and fall at Ramothgilead? And one spake saying after this manner, and another saying after that manner. Then there came out a spirit, and stood before the LORD, and said, I will entice him. And the LORD said unto him, Wherewith? And he said, I will go out, and be a lying spirit in the mouth of all his prophets. And the Lord said, Thou shalt entice him, and thou shalt also prevail: go out, and do even so. Now therefore, behold, the LORD hath put a lying spirit in the mouth of these thy prophets, and the LORD hath spoken evil against thee.
And some of them of understanding shall fall, to try them, and to purge, and to make them white, even to the time of the end: because it is yet for a time appointed. And the king shall do according to his will; and he shall exalt himself, and magnify himself above every god, and shall speak marvellous things against the God of gods, and shall prosper till the indignation be accomplished: for that that is determined shall be done. Neither shall he regard the God of his fathers, nor the desire of women, nor regard any god: for he shall magnify himself above all. But in his estate shall he honour the God of forces: and a god whom his fathers knew not shall he honour with gold, and silver, and with precious stones, and pleasant things.
For many shall come in my name, saying, I am Christ; and shall deceive many. And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet. For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places. All these are the beginning of sorrows. Then shall they deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations for my name's sake. And then shall many be offended, and shall betray one another, and shall hate one another. And many false prophets shall rise, and shall deceive many. And because iniquity shall abound, the love of many shall wax cold.
For though there be that are called gods, whether in heaven or in earth, (as there be gods many, and lords many,) But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.

CHAPTER 4
1Ti 4:1-16. Prediction of a Coming Departure from the Faith: Timothy's Duty as to It: General Directions to Him.
The "mystery of iniquity" here alluded to, and already working (2Th 2:7), stands opposed to the "mystery of godliness" just mentioned (1Ti 3:16).
1. Now—Greek, "But." In contrast to the "mystery of godliness."
the Spirit—speaking by the prophets in the Church (whose prophecies rested on those of the Old Testament, Da 7:25; 8:23, &c.; 11:30, as also on those of Jesus in the New Testament, Mt 24:11-24), and also by Paul himself, 2Th 2:3 (with whom accord 2Pe 3:3; 1Jo 2:18; Jude 18).
expressly—"in plain words." This shows that he refers to prophecies of the Spirit then lying before him.
in the latter times—in the times following upon the times in which he is now writing. Not some remote future, but times immediately subsequent, the beginnings of the apostasy being already discernible (Ac 20:29): these are the forerunners of "the last days" (2Ti 3:1).
depart from the faith—The apostasy was to be within the Church, the faithful one becoming the harlot. In 2Th 2:3 (written earlier), the apostasy of the Jews from God (joining the heathen against Christianity) is the groundwork on which the prophecy rises; whereas here, in the Pastoral Epistles, the prophecy is connected with Gnostic errors, the seeds of which had already been sown in the Church [Auberlen] (2Ti 2:18). Apollonius Tyanæus, a heretic, came to Ephesus in the lifetime of Timothy.
giving heed—(1Ti 1:4; Tit 1:14).
seducing spirits—working in the heretical teachers. 1Jo 4:2, 3, 6, "the spirit of error," opposed to "the spirit of truth," "the Spirit" which "speaketh" in the true prophets against them.
doctrines of devils—literally "teachings of (that is suggested by) demons." Jas 3:15, "wisdom … devilish"; 2Co 11:15, "Satan's ministers."
2. Rather translate, "Through (literally, 'in'; the element in which the apostasy has place) the hypocrisy of lying speakers"; this expresses the means through which "some shall (be led to) depart from the faith," namely, the reigned sanctity of the seducers (compare "deceivers," Tit 1:10).
having their conscience seared—Greek, "having their own conscience," &c., that is, not only "speaking lies" to others, but also having their own conscience seared. Professing to lead others to holiness, their own conscience is all the while defiled. Bad consciences always have recourse to hypocrisy. As faith and a good conscience are joined (1Ti 1:5); so hypocrisy (that is, unbelief, Mt 24:5, 51; compare Lu 12:46) and a bad conscience here. Theodoret explains like English Version, "seared," as implying their extreme insensibility; the effect of cauterizing being to deaden sensation. The Greek, however, primarily means "branded" with the consciousness of crimes committed against their better knowledge and conscience, like so many scars burnt in by a branding iron: Compare Tit 1:15; 3:11, "condemned of himself." They are conscious of the brand within, and yet with a hypocritical show of sanctity, they strive to seduce others. As "a seal" is used in a good sense (2Ti 2:19), so "a brand" in a bad sense. The image is taken from the branding of criminals.
3. Sensuality leads to false spiritualism. Their own inward impurity is reflected in their eyes in the world without them, and hence their asceticism (Tit 1:14, 15) [Wiesinger]. By a spurious spiritualism (2Ti 2:18), which made moral perfection consist in abstinence from outward things, they pretended to attain to a higher perfection. Mt 19:10-12 (compare 1Co 7:8, 26, 38) gave a seeming handle to their "forbidding marriage" (contrast 1Ti 5:14); and the Old Testament distinction as to clean and unclean, gave a pretext for teaching to "abstain from meats" (compare Col 2:16, 17, 20-23). As these Judaizing Gnostics combined the harlot or apostate Old Testament Church with the beast (Re 17:3), or Gnostic spiritualizing anti-Christianity, so Rome's Judaizing elements (1Ti 4:3) shall ultimately be combined with the open worldly-wise anti-Christianity of the false prophet or beast (1Ti 6:20, 21; Col 2:8; 1Jo 4:1-3; Re 13:12-15). Austerity gained for them a show of sanctity while preaching false doctrine (Col 2:23). Eusebius [Ecclesiastical History, 4.29] quotes from Irenæus [1.28] a statement that Saturninus, Marcion, and the Encratites preached abstinence from marriage and animal meats. Paul prophetically warns against such notions, the seeds of which already were being sown (1Ti 6:20; 2Ti 2:17, 18).
to be received—Greek, "to be partaken of."
of them—literally, (created and designed) "for them," Though all (even the unbelieving, Ps 104:14; Mt 5:45) are partakers in these foods created by God, "they which believe" alone fulfil God's design in creation by partaking of them with thanksgiving; as opposed to those who abstain from them, or in partaking of them, do not do so with thanksgiving. The unbelieving have not the designed use of such foods by reason of their "conscience being defiled" (Tit 1:15). The children of God alone "inherit the earth"; for obedience is the necessary qualification (as it was in the original grant of the earth to Adam), which they alone possess.
and know the truth—explanatory and defining who are "they which believe." Translate as Greek, "and have full knowledge of the truth" (see on Php 1:9). Thus he contradicts the assumption of superior knowledge and higher moral perfection, put forward by the heretics, on the ground of their abstinence from marriage and meats. "The truth" stands in opposition to their "lies" (1Ti 4:2).
4, 5. Translate as Greek, "Because" (expressing a reason resting on an objective fact; or, as here, a Scripture quotation)—"For" (a reason resting on something subjective in the writer's mind).
every creature … good—(Ge 1:31; Ro 14:14, 20). A refutation by anticipation of the Gnostic opposition to creation: the seeds of which were now lurking latently in the Church. Judaism (Ac 10:11-16; 1Co 10:25, 26) was the starting-point of the error as to meats: Oriental Gnosis added new elements. The old Gnostic heresy is now almost extinct; but its remains in the celibacy of Rome's priesthood, and in its fasts from animal meats, enjoined under the penalty of mortal sin, remain.
if … with thanksgiving—Meats, though pure in themselves, become impure by being received with an unthankful mind (Ro 14:6; Tit 1:15).
5. sanctified—"hallowed"; set apart as holy for the use of believing men: separated from "the creature," which is under the bondage of vanity and corruption (Ro 8:19, &c.). Just as in the Lord's Supper, the thanksgiving prayer sanctifies the elements, separating them from their naturally alien position in relation to the spiritual world, and transferring them to their true relation to the new life. So in every use of the creature, thanksgiving prayer has the same effect, and ought always to be used (1Co 10:30, 31).
by the word of God and prayer—that is, "by means of intercessory prayer" (so the Greek)—that is, consecratory prayer in behalf of "the creature" or food—that prayer mainly consisting of "the word of God." The Apostolic Constitutions [7.49], give this ancient grace, almost wholly consisting of Scripture, "Blessed art thou, O Lord, who feedest me from my youth, who givest food to all flesh: Fill our hearts with joy and gladness, that we, having all sufficiency, may abound unto every good work in Christ Jesus our Lord, through whom glory, honour, and might, be to thee for ever. Amen." In the case of inspired men, "the word of God" would refer to their inspired prayers (1Ki 17:1); but as Paul speaks in general, including uninspired men's thanksgiving for meals, the "word of God" more probably refers to the Scripture words used in thanksgiving prayers.
6. If thou put … in remembrance—rather as Greek, "If thou suggest to (bring under the notice of) the brethren," &c.
these things—namely, the truths stated in 1Ti 4:4, 5, in opposition to the errors foretold, 1Ti 4:1-3.
minister—"servant."
nourished up—The Greek is present, not past: "continually being nourished in" (2Ti 1:5; 3:14, 15).
the words of faith—rather, "the words of the faith" (compare 1Ti 4:12).
good doctrine—"the good teaching." Explanatory of "the faith," in opposition to the "teachings of demons" (English Version, "doctrines of devils," 1Ti 4:1) which Timothy was to counteract. Compare "sound doctrine" (1Ti 1:10; 6:3; Tit 1:9; 2:1).
whereunto thou hast attained—"the course of which thou hast followed"; hast followed along by tracing its course and accompanying it [Alford]. Thou hast begun to follow up [Bengel]. The same Greek occurs, "thou hast fully known" (2Ti 3:10), "having had perfect understanding" (Lu 1:3). It is an undesigned coincidence that the Greek verb is used only by Paul and Paul's companion, Luke.
7. refuse—reject, avoid, have nothing to do with (2Ti 2:23; Tit 3:10).
old wives' fables—anile myths (1Ti 1:4, 9; Tit 1:14). They are "profane," because leading away from "godliness" or "piety" (1Ti 1:4-7; 6:20; 2Ti 2:16; Tit 1:1, 2).
exercise thyself—literally, "exercise thyself" as one undergoing training in a gymnasium. Let thy self-discipline be not in ascetical exercises as the false teachers (1Ti 4:3, 8; compare 2Ti 2:22, 23; Heb 5:14; 12:11), but with a view to godliness or "piety" (1Ti 6:11, 12).
8. profiteth little—Greek, "profiteth to (but) a small extent." Paul does not deny that fasting and abstinence from conjugal intercourse for a time, with a view to reaching the inward man through the outward, do profit somewhat, Ac 13:3; 1Co 7:5, 7; 9:26, 27 (though in its degenerate form, asceticism, dwelling solely on what is outward, 1Ti 4:3, is not only not profitable but injurious). Timothy seems to have had a leaning to such outward self-discipline (compare 1Ti 5:23). Paul, therefore, while not disapproving of this in its due proportion and place, shows the vast superiority of godliness or piety, as being profitable not merely "to a small extent," but unto all things; for, having its seat within, it extends thence to the whole outward life of a man. Not unto one portion only of his being, but to every portion of it, bodily and spiritual, temporal and eternal [Alford]. "He who has piety (which is 'profitable unto all things') wants nothing needed to his well-being, even though he be without those helps which, 'to a small extent,' bodily exercise furnishes" [Calvin]. "Piety," which is the end for which thou art to "exercise thyself" (1Ti 4:7), is the essential thing: the means are secondary.
having promise, &c.—Translate as Greek, "Having promise of life, that which now is, and that which is to come." "Life" in its truest and best sense now and hereafter (2Ti 1:1). Length of life now so far as it is really good for the believer; life in its truest enjoyments and employments now, and life blessed and eternal hereafter (Mt 6:33; Mr 10:29, 30). "Now in this time" (Ps 84:11; 112:1-10; Ro 8:28; 1Co 3:21, 22, "all things are yours … the world, life … things present, things to come"). Christianity, which seems to aim only at our happiness hereafter, effectually promotes it here (1Ti 6:6; 2Pe 1:3). Compare Solomon's prayer and the answer (1Ki 3:7-13).
9. (1Ti 1:15). This verse (Greek), "faithful is the saying, " &c. confirms the assertion as to the "promise" attached to "godliness," 1Ti 4:8, and forms a prefatory introduction to 1Ti 4:10, which is joined to 1Ti 4:9 by "For." So 2Ti 2:11. Godly men seem to suffer loss as to this life: Paul hereby refutes the notion [Bengel]. "God is the Saviour specially of those that believe" (1Ti 4:10), both as to "the life that now is," and also as to "the life which is to come" (1Ti 4:8).
10. therefore—Greek, "with a view to this." The reason why "we both ('both' is omitted in the oldest manuscripts) labor (endure hardship) and suffer reproach (some oldest manuscripts read 'strive') is because we have rested, and do rest our hope, on the living (and therefore, life-giving, 1Ti 4:8) God."
Saviour—even in this life (1Ti 4:8).
specially of those that believe—Their "labor and reproach" are not inconsistent with their having from the living God, their Saviour, even the present life (Mr 10:30, "a hundred fold now in this time … with persecutions"), much more the life to come. If God is in a sense "Saviour" of unbelievers (1Ti 2:4, that is, is willing to be so everlastingly, and is temporally here their Preserver and Benefactor), much more of believers. He is the Saviour of all men potentially (1Ti 1:15); of believers alone effectually.
11. These truths, to the exclusion of those useless and even injurious teachings (1Ti 4:1-8), while weighing well thyself, charge also upon others.
12. Let no man despise thy youth—Act so as to be respected in spite of thy youth (1Co 16:11; Tit 2:15); compare "youthful" as to Timothy (2Ti 2:22). He was but a mere youth when he joined Paul (Ac 16:1-3). Eleven years had elapsed since then to the time subsequent to Paul's first imprisonment. He was, therefore, still young; especially in comparison with Paul, whose place he was filling; also in relation to elderly presbyters whom he should "entreat as a father" (1Ti 5:1), and generally in respect to his duties in rebuking, exhorting, and ordaining (1Ti 3:1), which ordinarily accord best with an elderly person (1Ti 5:19).
be thou an example—Greek, "become a pattern" (Tit 2:7); the true way of making men not to despise (slight, or disregard) thy youth.
in word—in all that thou sayest in public and private.
conversation—that is, "behavior" the Old English sense of the word.
in charity … faith—the two cardinal principles of the Christian (Ga 5:6). The oldest manuscripts omit, "in spirit."
in purity—simplicity of holy motive followed out in consistency of holy action [Alford] (1Ti 5:22; 2Co 6:6; Jas 3:17; 4:8; 1Pe 1:22).
13. Till I come—when Timothy's commission would be superseded for the time by the presence of the apostle himself (1Ti 1:3; 3:14).
reading—especially in the public congregation. The practice of reading Scripture was transferred from the Jewish synagogue to the Christian Church (Lu 4:16-20; Ac 13:15; 15:21; 2Co 3:14). The New Testament Gospel and Epistles being recognized as inspired by those who had the gift of discerning spirits, were from the first, according as they were written, read along with the Old Testament in the Church (1Th 5:21, 27; Col 4:16), [Justin Martyr, Apology, 1.67]. I think that while public reading is the prominent thought, the Spirit intended also to teach that Scripture reading in private should be "the fountain of all wisdom from which pastors ought to draw whatever they bring before their flock" [Alford].
exhortation—addressed to the feelings and will with a view to the regulation of the conduct.
doctrine—Greek (ministerial), "teaching" or instruction. Addressed to the understanding, so as to impart knowledge (1Ti 6:2; Ro 12:7, 8). Whether in public or private, exhortation and instruction should be based on Scripture reading.
14. Neglect not the gift—by letting it lie unused. In 2Ti 1:6 the gift is represented as a spark of the Spirit lying within him, and sure to smoulder by neglect, the stirring up or keeping in lively exercise of which depends on the will of him on whom it is bestowed (Mt 25:18, 25, 27, 28). The charism or spiritual gift, is that of the Spirit which qualified him for "the work of an evangelist" (Eph 4:11; 2Ti 4:5), or perhaps the gift of discerning spirits, specially needed in his function of ordaining, as overseer [Bishop Hinds].
given thee—by God (1Co 12:4, 6).
by prophecy—that is, by the Holy Spirit, at his general ordination, or else consecration, to the special see of Ephesus, speaking through the prophets God's will to give him the graces needed to qualify him for his work (1Ti 1:18; Ac 13:1-3).
with … laying on of … hands—So in Joshua's case (Nu 27:18-20; De 34:9). The gift was connected with the symbolical act of laying on hands. But the Greek "with" implies that the presbyter's laying on hands was the mere accompaniment of the conferring of the gift. "By" (2Ti 1:6) implies that Paul's laying on his hands was the actual instrument of its being conferred.
of the presbytery—In 2Ti 1:6 the apostle mentions only his own laying on of hands. But there his aim is to remind Timothy specially of the part he himself took in imparting to him the gift. Here he mentions the fact, quite consistent with the other, that the neighboring presbyters took part in the ordination or consecration, he, however, taking the foremost part. Paul, though having the general oversight of the elders everywhere, was an elder himself (1Pe 5:1; 2Jo 1). The Jewish council was composed of the elders of the Church (the presbytery, Lu 22:66; Ac 22:5), and a presiding rabbi; so the Christian Church was composed of apostles, elders, and a president (Ac 15:16). As the president of the synagogue was of the same order as his presbyters, so the bishop was of the same order as his presbyters. At the ordination of the president of the synagogue there were always three presbyters present to lay on hands, so the early Church canons required three bishops to be present at the consecration of a bishop. As the president of the synagogue, so the bishop of the Church alone could ordain, he acting as the representative, and in the name of the whole presbytery [Vitringa]. So, in the Anglican Church, the bishop ordains, the presbyters or priests present joining with him in laying on hands.
15. Meditate—Greek, "Meditate CAREFULLY upon" (Ps 1:2; 119:15; compare "Isaac," Ge 24:63).
these things—(1Ti 4:12-14). As food would not nourish without digestion, which assimilates the food to the substance of the body, so spiritual food, in order to benefit us, needs to be appropriated by prayerful meditation.
give thyself wholly to—literally, "BE in these things"; let them engross thee wholly; be wholly absorbed in them. Entire self-dedication, as in other pursuits, so especially in religion, is the secret of proficiency. There are changes as to all other studies, fashionable to-day, out of fashion to-morrow; this study alone is never obsolete, and when made the all-engrossing aim sanctifies all other studies. The exercise of the ministry threatens the spirit of the ministry, unless it be sustained within. The minister must be first his own scholar before he can be another's teacher.
profiting—Greek, "progress" towards perfection in the Christian life, and especially towards the fullest realization of the ideal of a Christian minister (1Ti 4:12).
may appear to all—not for thy glory, but for the winning of souls (Mt 5:16).
16. Take heed—Give heed (Ac 3:5).
thyself, and … doctrine—"and unto thy teaching." The two requisites of a good pastor: His teaching will be of no avail unless his own life accord with it; and his own purity of life is not enough unless he be diligent in teaching [Calvin]. This verse is a summary of 1Ti 4:12.
continue in them—(2Ti 3:14).
in doing this—not "by doing this," as though he could save himself by works.
thou shalt … save thyself, and them that hear thee—(Eze 33:9; Jas 5:20). In performing faithfully his duty to others, the minister is promoting his own salvation. Indeed he cannot "give heed unto the teaching" of others, unless he be at the same time "giving heed unto himself."
