22:32 {11} But I have prayed for thee, that thy faith fail not: and when thou art converted, strengthen thy brethren.
(11) It is through the prayers of Christ that the elect never utterly fall away from the faith: and because of this they should encourage one another on.
22:31-34 Simon, Simon. For the warning to Peter of his Denial of the Lord, see Mt 26:31-35. Compare Mr 14:27-31.
22:32 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.
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.
