Peter was a man of resolute character, bold and decisive. He was easily the leader of the twelve. Honest-hearted and warmly attached to Christ, he believed himself immovably loyal; yet in the hour of temptation he proved unstable and weak. Jesus knew his heart and warned him against over-confidence in his own loyalty. "I have been praying for thee," he said, "that thy faith fail not." He needed this divine strengthening. His faith had failed once before in a crisis (see Matt. 14:29), and what he needed to confirm him now was the "power from on high" which would come later. The tempter was to sift all the disciples, and Jesus foresaw Peter's weakness, but he was preserved from falling by this special intercession. His case shows, perhaps more completely than any other in the New Testament, the weakness of the natural and the strength of the spiritual man. Even at the moment of his denial of Christ, it needed but a glance from the eye of his Lord to make him instantly repentant. After the enduement with the Holy Ghost, he stood forth as the leader of the apostles, faithful unto death.
