53:5 It was after Peter had been led to self-renunciation and entire reliance upon divine power, that he received his call to act as an undershepherd. Christ had said to Peter, before his denial of Him, "When thou art converted, strengthen thy brethren." Luke 22:32. These words were significant of the wide and effectual work which this apostle was to do in the future for those who should come to the faith. For this work, Peter's own experience of sin and suffering and repentance had prepared him. Not until he had learned his weakness, could he know the believer's need of dependence on Christ. Amid the storm of temptation he had come to understand that man can walk safely only as in utter self-distrust he relies upon the Saviour.
