If we suffer, we shall also reign with him. If we deny him, he will also deny us.

“Knowing, then, that "God is not mocked," we ought to walk worthy of His commandment and glory. In like manner should the deacons be blameless before the face of His righteousness, as being the servants of God and Christ, and not of men. They must not be slanderers, double-tongued, or lovers of money, but temperate in all things, compassionate, industrious, walking according to the truth of the Lord, who was the servant of all. If we please Him in this present world, we shall receive also the future world, according as He has promised to us that He will raise us again from the dead, and that if we live worthily of Him, "we shall also reign together with Him," provided only we believe.”

“Accordingly, I beseech you, let us so perform all our actions that we may not fail to obtain such glory as this. To obtain it is by no means difficult, if we desire it, or arduous, if we apply ourselves to it. For, "If we endure, we shall also reign." What is the meaning of "If we endure"? If we patiently bear tribulations and persecutions; if we walk the narrow path. The narrow path is unattractive by nature but becomes easy when we choose to follow it, because of our hope for the future.”

“In him therefore is our hope of eternal life, and in him also is the pattern of our patience. "If we suffer with him, we shall also reign with him," since, as the apostle says, "those who claim that they remain in Christ ought themselves to walk just as Christ walked." Otherwise we are appearing under the likeness of a false profession if we do not follow the commands of him in whose name we glory. And these would indeed not be burdensome to us and would free us from all dangers, if we would only love what he commands us to love.”

“And again he saith, "If we endure with Him, we shall reign with Him." And again he saith, "He shall change the body of our humility, and shall make it like unto His glorious body, according to His great power through which all things are subject unto Him." Now therefore unto this greatness will the disciple attain if he travelleth completely in his Master's footsteps, but in order that thou mayest not think that this portion of honour came only to the Apostles, Paul said, "If we suffer with Him, we shall also be glorified with Him, and if we endure we shall also reign with Him."”

“Above, the preparation for martyrdom was set forth; here the exhortation to it is set forth, and first he sets forth in advance the example of the reward; second, the example of martyrdom, at in which I labor; third, he shows the connection of the reward to martyrdom, at faithful is the saying. For the reward of the precious death of martyrdom is the glorious resurrection, the example of which preceded in Christ our head. And therefore he says be mindful, etc., as if to say: our Lord Jesus Christ — supply: keep him in mind against tribulations. Prov. 3:6: In all your ways think on him, and he will direct your steps. For there are many things to be thought about in him, but especially the resurrection. To this all things are ordered, and especially the whole state of the Christian religion. Rom. 10:9: If you confess with your mouth the Lord Jesus, and believe in your heart that God raised him from the dead, you will be saved. And note that he says raised up, because although the Father raised him, yet he also rose by his own power, and he is the first of those rising, 1 Cor. 15:20. But because he rose according to human nature, and died, of the seed of David. Rom. 1:3: who was made to him of the seed of David according to the flesh, et cetera. According to my Gospel, that is, preached by me. 1 Cor. 15:1: But I make known to you the Gospel which I preached to you. He who preaches the Gospel is a minister of the Gospel, just as he who baptizes is a minister of Baptism. Yet it cannot be said "my Baptism," but "my Gospel" can be said thus. And this is so because exhortation and solicitude contribute much. Then, when he says in which I labor, he shows himself as an example of martyrdom, and first its punishment; second its cause, at therefore all things. Now he shows three things to be in the punishment, namely bitterness, reproach, and constancy. Bitterness, when he says in which, namely in preaching the Gospel, or for which I labor, that is, I am afflicted, and this even unto bonds, because when he wrote this epistle, he was at Rome in bonds. Eph., last chapter: the ministry of the Gospel, for which I act as ambassador in a chain. Reproach as regards unbelievers, when he says as an evildoer. For Christians then were reputed the worst. Lc. 9: Blessed will you be when men hate you, and separate you, and reproach you, et cetera. Christ too was condemned, as an evildoer. Is. 53:12: and he was reputed with the wicked. But he shows constancy, when he says but the word of God, et cetera. For although the body is bound, yet the word of God is not bound, because preaching came from the will of the apostle, which is free, especially on account of the efficacy of charity, which fears nothing. Rom. 8:38: For I am certain that neither death, nor life, et cetera. Because, as it is said in 1 Jn. 3:20, God is greater than our heart. And it is said that, existing in bonds, he converted many. Then, when he says therefore I endure all things, he shows the cause, because it is not the punishment that makes a martyr, but the cause. Now the cause of martyrdom is twofold, namely for the sake of divine honor, and the salvation of one's neighbor. For the sake of God indeed, because Rom. 8:36: for your sake we are put to death all the day long. For the salvation of neighbors, because he says here for the sake of the elect. Jn. 15:13: Greater love has no one, than that someone lay down his life for his friends. 1 Jn. 3:16: because he laid down his life for us, and we ought to lay down our lives for the brethren. And he says for the sake of the elect, because whatever good things happen, they redound especially to the good of the elect, not of the reprobate. And how? That they too may obtain salvation. But is the Passion of Christ sufficient? It must be said that it is, effectively, but the passion of the apostle was expedient in two ways. First, because it gave an example of persisting in the faith; second, because the faith was confirmed, and from this they were led to salvation. And this in Christ, that is, which comes to us through him. Matt. 1:21: for he will save the people from their sins. And this not only salvation, present in grace, but also with heavenly glory. Matt. ch. 5:12: your reward is abundant in the heavens. Then, when he says faithful is the saying, he sets forth the connection of the reward to the merit of martyrdom. And first he sets forth the attestation; second, the consequence, at for if we have died together; third, he confirms it by testimony, at these things put in remembrance. He says therefore faithful is the saying, that is, the word which I shall say is faithful. Apoc., last chapter: these words are most faithful, et cetera. Then, when he says for if, et cetera, he sets forth the consequence. And first concerning the reward of the good; second concerning the punishment of the evil, at if we deny. In the reward of the good there are two things, namely restoration through the resurrection, and the addition of glory to which they will rise. And therefore first he shows that through Christ one comes to the restoration of life; second that through him one comes to the resurrection, at if we endure. He says therefore if we have died together, namely with Christ, and this through the reception of the sacrament in Baptism. Rom. 6:4: for we are buried together with him through Baptism into death. Likewise through penance, by mortifying ourselves. Gal. 6:24: those who are Christ's have crucified their flesh with the vices and lusts. Likewise by dying for the confession of truth, just as Christ also did. Ps. 115:15: Precious in the sight of the Lord is the death of his saints. If therefore we have died together, we shall also live together, that is, just as he rose, so shall we too. Rom. 6:5: If we have been planted together with the likeness of his death, we shall be also of his resurrection. Then he treats of the glory, which the saints merit through the ignominy of death. Lc., last chapter: was it not necessary that Christ should suffer these things? And therefore he says if we endure, namely afflictions and reproaches patiently, we shall reign together, that is, we shall arrive at the kingdom together with him. Matt. 5:10: Blessed are those who persecution, et cetera. Then, when he says if we deny, he shows the consequence as regards punishments. Now one can sin against the faith in two ways: first, by denying it outwardly; second, by laying it aside inwardly. As to the first, he says if we deny, namely before others, he will deny us in judgment. Matt. 25:12: Amen I say to you, I do not know you. To deny is not to acknowledge them to be of his own sheep. As to the second, he says if we do not believe, that is, if we cast faith from the heart, he remains faithful, that is, he holds to his own faithfulness. Hence he remains faithful in his faith, because faith is nothing other than participation in, or adherence to, the truth. But he himself is the very truth, which cannot deny itself. Therefore he is not omnipotent. I respond. From this he is omnipotent, that he cannot deny himself. For to be able to fail pertains rather to impotence, because that something should fail from its own being is through a weakness of its own power. But for Christ to deny himself is to fail from himself; this very fact, therefore, that he cannot deny himself, is the reason of perfect power. Hence sin does not fall upon him, as has been said, nor can he deny his power and his justice without punishing. Matt., last chapter: but he who does not believe will be condemned. But can God not remit the punishment to someone? He can indeed according to the order of his wisdom, but against the order of wisdom and justice, he cannot. Then, when he says these things put in remembrance, et cetera, he confirms it by testimony; as if to say: I admonish along with others, that you may always keep it in your heart, testifying before God, that is, bringing forward as witness him before whom I speak. Then, when he says do not with words, he shows how he resists unbelievers, because first he sets forth in advance the manner of resisting; second he shows what the things are which he resists, at profane. Likewise, first he excludes the undue manner of resisting; second he sets forth the due manner, at diligently. Concerning the first, first he excludes the undue manner; second he assigns the reason, at to nothing. He says therefore do not contend with words. Contention implies a contending in words. It can therefore be understood in two ways, because one speaking with acrimony is depraved in two ways. In one way, if by this one inclines to the favor of falsity, as when someone attacks the truth with a confident clamor. In another way, on account of disorder, as when one uses acrimony either beyond the due measure, or contrary to the quality of the person. But if it is done moderately, and with due circumstances, and on behalf of the truth, it is not a sin. And thus in rhetoric it is one instrument of exhortation. Yet in sacred Scripture it is taken according as it implies disorder. 1 Cor. 11:16: If anyone seems to be contentious among you, we have no such custom, nor does the Church of God. And he says with words, because some dispute only with words of reproach. And this properly is to contend. If this is done not with words only but with true reasons, this is to dispute, not to contend. Then, when he says it is useful for nothing, he shows the reason for the teaching. For moderate disputation, when it is done with reason, is useful for instruction; but when it is with words only, then it is litigious. Therefore he says but to the subverting, and this in two ways: in one way, while what is certain comes into doubt; in another way, because the hearers are scandalized. Prov. 14:23: Where there are many words, there is frequently poverty; hence Jas. 3:16: Where there is envy and contention, there is inconstancy and every wicked work. But should one not dispute about the faith before the people without contention? I respond. A distinction must be made, on the part of the hearers, because either they are being solicited by unbelievers, and then public disputation is useful: because through this the simple are made more instructed when they see those who err refuted. But if they are not being solicited by unbelievers, then disputation is not useful, but dangerous. Likewise a distinction must be made on the part of the one disputing, because if the disputant is prudent, so that he clearly refutes the adversary, then he ought to dispute publicly; but if not, in no way. Then, when he says diligently take heed to yourself, he sets forth the due manner of resisting. And first as regards right intention; second as regards right action; third as regards right doctrine. For he who wishes to dispute must first examine his own intention, whether he is moved by good zeal. Therefore he says to show himself approved to God, who indeed tests the heart. 2 Cor. 10:18: For it is not he who commends himself that is approved, but he whom God commends. Ps. 16:3: You have proved my heart, and visited it by night. Likewise, that he confirm through his works the doctrine which he preaches with his mouth, which unless he does, he is worthy of confusion. Hence he says a workman that need not be ashamed, as if to say: do these things, and thus you will not be put to confusion. Likewise, that he rightly handle the word of truth, teaching things true and useful to the hearers. Hence he adds rightly handling the word of truth, not seeking gain and glory. 2 Cor. 2:17: We are not like many, adulterating the word of God, but out of sincerity, as from God, in the sight of God, we speak in Christ.”

“If we suffer,.... With him, with Christ, as in Rom 8:17 all the elect suffered with Christ when he suffered; they suffered in him the whole penalty of the law, all the righteousness, strictness, and severity of it; and they are partakers of the benefits of his sufferings, as peace, pardon, righteousness, redemption, and everlasting salvation. And such being called by grace, and having made a profession of Christ, they suffer shame and reproach, loss of credit and reputation, and sometimes loss of goods, and corporeal punishment, and even death itself: but though they do, and if they should, they may be satisfied of the truth of this, we shall also reign with him; they reign with him now in the kingdom of grace; grace reigns in their hearts, where Christ, the King of glory, has entered, and has set up his throne, and where he dwells by faith, they being made kings and priests unto God by him; and they shall reign with him in his kingdom here on earth, for the space of a thousand years; and they shall reign with him in glory to all eternity: this is certain, for this kingdom is prepared for them, it is given to them, they are called unto it, and have both a right unto, and meetness for it; see Rom 8:17, if we deny him, he also will deny us: there is a denying of Christ in words; so it is denied by the Jews that Christ is come in the flesh, and that Jesus is the Messiah; and some that have bore the Christian name, though very unworthily, have denied his true deity, his real humanity, proper sonship, and the efficacy of his blood, righteousness, and sacrifice, for pardon, justification, and atonement: and there is a denying of him in works; so some that profess to know him, and do own him in his person and offices, yet in works deny him; their conversation is not becoming their profession of him; they have the form of godliness, but deny the power of it: there is a secret and silent denying of him, when men are ashamed of him, and do not confess him; and there is an open denying of him, by such who set their mouth against the heavens, and their tongue walketh throughout the earth; there is a partial denying of Christ, which was Peter's case, though his faith in him, and love to him, were not lost; and there is a total denying of him, a thorough apostasy, and from which there is no recovery; and if there be any such apostates among those who have named the name of Christ, he will deny them, he will not own them for his another day; he will set them at his left hand; he will declare he knows them not, and will banish them from his presence for evermore. This is another branch of the faithful saying; this will certainly be the case; Christ himself has said it, Mat 10:33.”

“suffer--rather, as the Greek is the same as in Ti2 2:10, "If we endure (with Him)" (Rom 8:17). reign with him--The peculiar privilege of the elect Church now suffering with Christ, then to reign with Him (see on Co1 6:2). Reigning is something more than mere salvation (Rom 5:17; Rev 3:21; Rev 5:10; Rev 20:4-5). deny--with the mouth. As "believe" with the heart follows, Ti2 2:12. Compare the opposite, "confess with thy mouth" and "believe in thine heart" (Rom 10:9-10). he also will deny us-- (Mat 10:33).”
