but I prayed for you, that your faith wouldn’t fail. You, when once you have turned again, establish your brothers.” – Luke 22:32
Peter was not to be lost in the terrible experience through which he was to pass. Christ had made intercession for him, and he would come again from the trial humbled, bruised, defeated, but saved, and a better man. Our Lord tells him here that after his restoration he should turn his experience to account in helping other souls. “Do thou, when once thou hast turned again, stablish thy brethren.” He would be able then to warn others of the dangers in which he had suffered so terribly. We can imagine Peter in after days counselling Christians against self-confidence and the other false steps which led to his own fall, and thus strengthening or stablishing them in safe ways. Then there is no doubt that his experience of penitence, and of the grace and love of Christ in that experience, enabled him to be a wise and safe guide to many another disciple who had fallen into sin and was seeking to be restored.
The lesson is important. All the lessons that God teaches us we should teach others. When we are helped it is that we may then help others. When God comforts us in any sorrow, He thereby ordains us to go forth to comfort others with the comfort wherewith we ourselves have been comforted of God. When we fall in temptation, and God lifts us up and restores us, He wants us to use our experience in helping other weak ones in their temptations.
O strengthen me, that while I stand
Firm on the rock, and strong in thee,
I may stretch out a loving hand
To wrestlers with the troubled sea.
