Luke 22:32

“But I have prayed for thee, etc.] 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 (<431701>John 17:1-26) 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 (<431709>John 17:9,11,15,17,20,24) 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 heard Jesus “always” John 11:42; it follows, therefore, that every prayer which he ever offered was answered; and it follows, as he asked here for a specific thing, that that thing was granted; and as he prayed that Peter’s faith might not utterly fail,…”

“But I have prayed for thee - Who wilt be in the greatest danger of all: that thy faith fail not - Altogether: and when thou art returned - From thy flight, strengthen thy brethren - All that are weak in faith; perhaps scandalized at thy fall. Luke 22:34”

“22:32 So when you have repented: This you is singular; it refers to Peter’s restoration after his denial of Jesus.”
