“And again: "For what is our hope, or joy, or crown of rejoicing? Are not even ye in the presence of our Lord God, Jesus Christ, at His coming? " Likewise: "Before God, even our Father, at the coming of the Lord Jesus Christ, with the whole company of His saints." He teaches them that they must "not sorrow concerning them that are asleep," and at the same time explains to them the times of the resurrection, saying, "For if we believe that Jesus died and rose again, even so them also which sleep in Jesus shall God bring with Him.”

“"To the end He may establish your hearts unblamable in holiness before our God and Father, at the coming of our Lord Jesus Christ with all His saints." He shows that love produces advantage to themselves, not to those who are loved. I wish, he says, that this love may abound, that there may be no blemish. He does not say to stablish you, but your hearts. "For out of the heart come forth evil thoughts." (Matt. xv. 19) For it is possible, without doing anything, to be a bad man; as for example, to have envy, unbelief, deceit, to rejoice at evils, not to be loving, to hold perverted doctrines, all these things are of the heart; and to be pure of these things is holiness. For indeed chastity is properly by preeminence called holiness, since fornication and adultery is also uncleanness. But universally all sin is uncleanness, and every virtue is purity. For, "Blessed," it is said, "are the pure in heart." (Matt. v. 8) By "the pure" He means those who are in every way pure. For other things also know how to pollute the soul, and no less. For that wickedness defiles the soul, hear the prophet, saying, "O Jerusalem, wash thine heart from wickedness." (Jer. iv. 14) And again, "Wash you, make you clean, put away the wickednesses from your souls." (Isa. i. 16, Sept) He did not say "fornications," so that not only fornication, but other things also defile the soul. "To establish your hearts," he says, "unblamable in holiness before our God and Father, at the coming of our Lord Jesus Christ with all His saints." Therefore Christ will then be a Judge, but not before Him (only), but also before the Father we shall stand to be judged. Or does he mean this, to be unblamable before God, as he always says, "in the sight of God," for this is sincere virtue-not in the sight of men? It is love then that makes them unblamable. For it does make men really unblamable.”

“He commemorated the tribulations they had suffered, and the remedy he proposed to offer them; here he shows how he had come to their aid by visiting through Timothy. And first he treats of the sending of the messenger; second, of the report made through him, at *but now*; third, of the effect of the report on the apostle, at *therefore we were comforted*. Likewise the first is divided into three, because first he sets forth the cause why he sent him; second, of what sort he sent; third, the cause on account of which he sent him. He says therefore *wherefore*, that is, because Satan hindered us, yet you are our glory; therefore not enduring the weight of love inclining toward you. Is. 1:14: they have become troublesome to me, etc. Gen. 45:1: he could not restrain himself any longer. *It pleased us*, namely Paul and Silvanus, *to remain at Athens alone, and we sent Timothy*, because he was most fitting for the apostle. Phil. 2:20: I have no one so like-minded, who with sincere affection is solicitous for you. 1 Cor. 4:17: I have sent to you Timothy, who is my most dear and faithful son in the Lord. *Brother*, through charity assisting. Prov. 18:19: a brother who is helped by a brother is like a strong city. *And minister*. It is the dignity of the Church. 2 Cor. 11:23: they are ministers of Christ, and I, etc. He sends him, moreover, to confirm them and to report back to himself. Then when he says *to confirm*, etc., he shows that he is sent to confirm. And first he does this; second, the reason for the confirmation is given, at *for you yourselves*. He says therefore *to confirm you and to exhort you*, because through exhortations a man's spirit is confirmed. Job 4:4: your words have confirmed those who were wavering. Lk. 22:32: and thou, once converted, confirm thy brethren. And you need to be exhorted for your faith, that no one be moved in these tribulations. Ecclus. 10:4: if the spirit of one having power ascend over thee, leave not thy place. There is, moreover, a twofold reason of confirmation. One from divine ordination: *for you yourselves know*, etc., as if to say: thus God willed, that through tribulations you should enter into heaven. Acts 14:22: through many tribulations you must enter into the kingdom of God, and 2 Tim. 3:12: all who wish to live piously in Christ Jesus shall suffer persecution. By this way Christ went. Lk. ult.: it behooved Christ to suffer and to rise, and thus to enter into his glory. The other reason is on the part of foretelling, because things foreseen strike less. Whence he says *for also when we were with*, etc., that is, because I foretold to you the tribulations which you have suffered in these years, *I sent to know*, etc., namely how firm you were in the faith. Prov. 27:23: diligently know the countenance of thy cattle, and consider thy flocks. *He who tempts*, namely the Devil. Matt. 4:3: the tempter approaching, Gloss: whose office it is to tempt. But against this: the world and the flesh tempt. Jas. 1:14: everyone is tempted by his own concupiscence, etc. Likewise Gen. 22:1: God tempted Abraham, etc. I answer. To tempt is to take a trial of something. In this it must be considered to what end he wishes to take it, and how. For this happens in two ways: either that he himself may know, or that he may cause another to know. In the first way God does not tempt, for he himself knows what is in man, Jn. 2:25. In the second way thus: for God tempted Abraham, namely that others might know his faith. But in the first way, to tempt happens in two ways, namely that he may promote to good, as a bishop examines those to be promoted; or someone tempts in order to deceive, and this is of the Devil, because namely he inquires into the condition of men, so that according to their diverse conditions he may lead them to the diverse vices to which they are prone. 1 Pet. 5:8: your adversary the Devil, etc. His office therefore is to tempt in order to deceive. The world and the flesh, however, are said to tempt materially, because through those things to which they themselves incline, a trial is taken of a man, whether he be firm toward the commandments of God and toward love. For if concupiscence should conquer, he does not perfectly love God. And likewise when the things of the world either terrify or affect him. *And in vain*, because if you do not resist temptation, your labor would be in vain. Gal. 4:11: I fear for you, lest perhaps I have labored among you without cause. Ez. 18:24: all his righteous deeds which he has done shall not be remembered. It is called *in vain*, however, with respect to the eternal reward; yet the good works done before a sin committed avail for something, because after repentance they revive, and one is disposed more easily to conversion. Then when he says *but now*, etc., he shows how Timothy reported their good things pertaining to God and to the apostle: to God, faith and charity. Gal. 6:15: in Christ Jesus, neither circumcision avails anything, nor uncircumcision, but a new creature. But faith, also to the apostle; whence he says *and that you have remembrance*. Ecclus. 49:1: the memory of Josias is like the composition of a work made, the work of the perfumer, etc. Prov. 10:7: the memory of the just is with praises, etc. *Desiring to see us, as we also you*. Augustine: hard is the mind which, when it does not wish to bestow love, refused even to return it. Is. 51:2: look unto Abraham your father, etc. Then when he says *therefore we were comforted*, a threefold effect of the report is set forth, namely of spiritual consolation, of thanksgiving, at *for what*, and of multiplied prayer, at *night*. He says therefore: because we have heard such things of you, although temporal necessities and bodily tribulations are pressing, yet *we were comforted*. Ps. 93:19: according to the multitude of my sorrows in my heart, thy comforts have gladdened my soul, etc. 2 Cor. 1:3: blessed be God and the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort, etc. And this *through your faith*, that is, hearing the firmness of your faith, *because we live*, etc. As if to say: I so love your state, that I reckon myself to live through it. Gen. 45:28: it is enough for me if my son Joseph yet lives. Then when he says *for what*, etc., the second effect of the report made is set forth, namely thanksgiving; as if to say: I am not sufficient to render any worthy thanksgiving to God for you. Mich. 6:6: what worthy thing shall I offer to the Lord, etc. Ps. 115:12: what shall I render to the Lord for all, etc. Thanksgivings are, however, to be referred *in all the joy*, which is altogether not exterior, but *with which we rejoice on account of you*, in conscience, *before our God*, who sees it. Or *before our God*, because it pleases God concerning one's neighbor. 1 Cor. 13:6: rejoices with the truth, etc. Then when he says *night*, etc., the third effect of the report is set forth, and first he sets forth the multiplicity of the prayer, second he shows what he prays for in praying, at *but himself*, etc. He says therefore: we give thanks for things past, yet we do not fail to pray for things future, indeed *night and day*, that is, in adversity and prosperity. Ps. 54:18: evening and morning and at noon I will declare, etc. *What is lacking*, etc. Not indeed those things which were of the necessity of faith, but certain secret things, which the apostle had not yet preached to them in their newness. 1 Cor. 3:1: I could not speak to you as to spiritual men, but as to carnal, etc. Jn. 16:12: I have many things to say to you, which not, etc. Then when he says *but may God himself*, etc., he shows what he prays for them. And concerning this he first shows what he asks, at *to confirm*. He asks, moreover, two things: one on his own part, that he might be able to go to them. Whence he says *may he himself, God and our Father*, etc. Jn. 20:17: I ascend to my Father and your Father, etc. Prov. 16:1: it is man's part to prepare the mind, but the Lord's to govern the tongue. The other on their part. Whence he says *but you may he multiply*, namely in faith. 2 Kings 24:3: may the Lord add to his people a hundredfold as many as they are, etc. And that merits may be increased. Whence he says *and may he make your charity abound*, which can always increase along the way. Col. 3:14: above all things have charity, which is the bond of perfection. And first, *toward one another*; second, *toward all*. Gal. 6:10: let us work good toward all, but especially toward those of the household of the faith. And he sets an example from himself, saying *as*, etc., as if to say: as I also love you. 2 Cor. 7:3: you are in our hearts, to die together and to live together. But to what end does he ask this? *To confirm your hearts without blame*, that is, that no one may be able to complain of you. Lk. 1:6: walking in all the commandments and justifications without blame. *And in holiness before God*, namely who sees the heart. Lk. 1:75: in holiness and justice before him, etc. And this appears *at the coming of our Lord Jesus Christ*, that he may find you holy; which coming will be *with all his saints*, that is, may you be in his sight, just as all the saints are before him.”

“To the end he may stablish your hearts,.... Which are very unstable and inconstant in their frames, and in the exercise of grace, and have need to be established in the love of God, against the fears of men, the frowns of the world, the temptations of Satan, and in, and with the doctrines of grace; See Gill on Th1 3:2, unblamable in holiness before God, even our Father. There is no holiness in men naturally; what is in them without the grace of God is only a show; true holiness is from the Spirit of God; and this is a stable thing in itself, and can never be removed or taken away; but the acts of it, through the prevalence of corruption, the force of Satan's temptations, and the snares of the world, are fickle and inconstant; and the saints need to be established in the discharge of duty, as well as in the exercise of grace: and whereas the apostle prays, that they might be "unblamable in holiness", the Alexandrian copy reads, "in righteousness" so one of Stephens's; it must be observed, that no man is perfectly holy in this life; no man is without sin in himself, or lives without the commission of it; holiness in the best is imperfect; no man, as yet, is in himself sanctified wholly; there is no unblamable holiness but in Christ; and in him the saints are without spot and blemish, who is their sanctification and their righteousness; but in themselves they are full of spots and stains; yet through the grace of God their hearts may be so established with principles of holiness, and they may be so assisted in the acts of it daily, as to give no just cause of blame to men, and so to behave as to approve themselves "before God", who sees the heart, and knows from what principles all actions flow: and this the apostle desires may be at the coming of our Lord Jesus; or unto the coming of him, as in Th1 5:23 Either at death, when he comes into his garden, and gathers his lilies, and takes his to himself to be for ever with him; or at the day of judgment, when he comes to judge the quick and dead; and which coming of his is certain, and will be quickly and suddenly, and with great glory and power: and, as it is here added, with all his saints; meaning either his holy angels, or rather the souls of his people, whom he will bring with him, and will raise their dead bodies, and reunite them to their souls, when they shall be for ever with him; and then shall they be unblamable in holiness, both in soul and body, and shall be presented by him, first to himself, and then to his Father, faultless, and without spot, or wrinkle, or any such thing. The Vulgate Latin, Arabic, and Ethiopic versions add, "Amen"; and so does Beza's ancient copy, and the Alexandrian manuscript. Next: 1 Thessalonians Chapter 4”

“To the end he may establish your hearts - Without love to God and man, there can be no establishment in the religion of Christ. It is love that produces both solidity and continuance. And, as love is the fulfilling of the law, he who is filled with love is unblamable in holiness: for he who has the love of God in him is a partaker of the Divine nature, for God is love. At the coming of our Lord - God is coming to judge the world; every hour that passes on in the general lapse of time is advancing his approach; whatsoever he does is in reference to this great event: and whatsoever we do should be in reference to the same. But who in that great day shall give up his accounts with joy? That person only whose heart is established in holiness before God; i.e., so as to bear the eye and strict scrutiny of his Judge. Reader, lay this to heart, for thou knowest not what a moment may bring forth. When thy soul departs from thy body it will be the coming of the Lord to thee.”

“your hearts--which are naturally the spring and seat of unholiness. before God, even our Father--rather, "before Him who is at once God and our Father." Before not merely men, but Him who will not be deceived by the mere show of holiness, that is, may your holiness be such as will stand His searching scrutiny. coming--Greek, "presence," or "arrival." with all his saints--including both the holy angels and the holy elect of men (Th1 4:14; Dan 7:10; Zac 14:5; Mat 25:31; Th2 1:7). The saints are "His" (Act 9:13). We must have "holiness" if we are to be numbered with His holy ones or "saints." On "unblameable," compare Rev 14:5. This verse (compare Th1 3:12) shows that "love" is the spring of true "holiness" (Mat 5:44-48; Rom 13:10; Col 3:14). God is He who really "stablishes"; Timothy and other ministers are but instruments (Th1 3:2) in "stablishing." Next: 1 Thessalonians Chapter 4”
