(32) I have prayed for thee.--The individualising pronoun is significant as indicating to the Apostle, who was most confident, it may be, of his claim to greatness, that he, of the whole company of the Twelve, was in the greatest danger. In the Greek the other pronoun also is emphatic. "It was I who prayed for thee." The prayer was answered, and the words that follow assume the answer as certain. In one sense "faith" did "fail" when the disciple denied his Lord; but repentance came after it, and a new power was gained through that weakness to make others strong. The word for "strengthen" does not meet us in the other Gospels, but is used frequently by St. Paul (Romans 1:11; 1Thessalonians 3:2, et al.), and twice by St. Peter himself (1Peter 5:10; 2Peter 1:12).

Verse 32. - But I have prayed for thee, that thy faith fail not. The prayer of Satan apparently was not refused. Jesus, however, says, that for one of that loved company, who he knew from his peculiar temperament was in especial peril, he had prayed. The prayer was answered thus: the temptation came to all the apostles; all fell; Peter, though, more disastrously by far than his brethren, but the result of the fall was not hopeless despair as in the case of Judas, but bitter remorse and a brave manly repentance. "It is said by Roman divines (e.g. Maldonatus, a Lapide, and Mai, here) that this prayer and precept of our Lord extends to all bishops of Rome as St. Peter's successors, and that in speaking to St. Peter our Lord spoke to them. Would they be willing to complete the parallel, and say that the bishops of Rome specially need prayer, because they deny Christ? Let them not take a part of it and leave the rest" (Bishop Wordsworth). When thou art converted. "Converted" must not be understood here in its technical sense; it should rather be translated, "And thou, when thou hast turned (i.e. to God) strengthen thy brethren."

22:21-38 How unbecoming is the worldly ambition of being the greatest, to the character of a follower of Jesus, who took upon him the form of a servant, and humbled himself to the death of the cross! In the way to eternal happiness, we must expect to be assaulted and sifted by Satan. If he cannot destroy, he will try to disgrace or distress us. Nothing more certainly forebodes a fall, in a professed follower of Christ, than self-confidence, with disregard to warnings, and contempt of danger. Unless we watch and pray always, we may be drawn in the course of the day into those sins which we were in the morning most resolved against. If believers were left to themselves, they would fall; but they are kept by the power of God, and the prayer of Christ. Our Lord gave notice of a very great change of circumstances now approaching. The disciples must not expect that their friends would be kind to them as they had been. Therefore, he that has a purse, let him take it, for he may need it. They must now expect that their enemies would be more fierce than they had been, and they would need weapons. At the time the apostles understood Christ to mean real weapons, but he spake only of the weapons of the spiritual warfare. The sword of the Spirit is the sword with which the disciples of Christ must furnish themselves.But I have prayed for thee,.... Christ prayed for all the apostles; but particularly for Peter, because he was in the greatest danger: whether the prayer Christ refers to was that in John 17:1 in which are many passages relating to the preservation, sanctification, final perseverance and glorification of the apostles, as well as of other saints, as in John 17:9 and so these words might be spoken a little after that prayer was ended, which was about this same time; or whether it was any other, and only mental, and not vocal, is not certain: however, the petition was,

that thy faith fail not; Satan in his temptations strikes principally at the faith of God's people; that being a grace which gives much glory to God, and in the exercise of which believers have much peace, joy, and comfort; both which he envies and grudges; and it is also a shield which keeps off, and quenches his fiery darts, and is a piece of armour he is sadly harassed with, and therefore endeavours all he can to weaken and destroy it, or wrest it out of their hands: but though, through the power of sin, and the force of temptation, it may fail as to some degree of the steadfastness of it, as to the acting and exercise of it, and as to the sense believers may have of it; yet never as to its principle, it being an irrevocable gift of God's grace; a work of his almighty power; a solid and substantial grace, even the substance of things hoped for; an immortal and incorruptible seed, and of which Christ is the author and finisher; and to nothing more is its security owing, than to the prayers of Christ, which are always heard, and to his powerful mediation, and prevalent intercession; Christ is the advocate of his people; he prays that they might have faith, and then he prays, that it may not fail; and it shall not, notwithstanding all the opposition of hell, and earth, unto it:

and when thou art converted, strengthen thy brethren: Peter was now a converted man, and had been for some years; but whereas he would fall by temptation into a very great sin of denying his Lord, and which was attended with such circumstances as made him look like an unconverted, and an unregenerate man; his recovery by the fresh exercise of faith in Christ, and repentance for his sins, is called conversion: and which was not his own act, but owing to the power and efficacy of divine grace; see Jeremiah 31:18. Some versions render it in the imperative, "in time, convert, turn, or return, and strengthen thy brethren"; as the Syriac, Arabic, and Persic versions: as he afterwards did: for whereas all the disciples forsook Christ, and fled, some one way, and some another, Peter, after his recovery, got them together again, and returned with them to Jerusalem; when they with him assembled together, till the third day Christ was risen: he strengthened their faith in the Messiah, and put them upon filling up the place of Judas, by choosing another apostle; and on the day of "Pentecost" preached a most excellent sermon, which as it was made useful for the conversion of three thousand sinners, was, doubtless, a means of confirming the minds of the disciples; and he has left two exceeding useful epistles for the strengthening of his brethren in all ages of time; the design of which is to establish the saints in faith and holiness, that they may not be drawn aside, and fall from the steadfastness of their faith, either by the lusts of the flesh, or by the persecutions of men, or by the error of the wicked.
