Now, that took faith. The idea of his just letting go the boat, and stepping down into the water! Why, that required faith. And there are a great many men today willing to become Christians if they can only just see how they are going to walk. They want to walk by sight. They do not want to walk by faith. It took faith for Peter to let go of the boat and take the first step on the water, but the Lord had bid him to do it, and he just did it; but after he began to sink he began to doubt, and called on the Lord to save him. “But when he saw the wind boisterous, he was afraid; and beginning to sink, he cried, saying: ‘Lord, save me.’” See! He began to sink when he took his eyes off his Master. Peter did not trust in Him. He did not have perfect faith. Now, the Lord says in Isaiah, twenty-sixth chapter and third verse: “Thou wilt keep him in perfect peace whose mind is stayed on Thee, because he trusteth in Thee.” Peter did not have perfect faith, because his mind was not stayed on Christ; he did not trust in Him. If Peter had trusted in the Lord he would not have sunk. The ship was in the midst of the sea; the wind was blowing quite a gale, and the waves were rolling high, and Peter began to tremble and doubt, and down he went. And a good many Christians follow his example. When it gets dark, when the wind begins to blow, and when the water rolls high about them, they begin to doubt--and down they go. Some one says if Peter had as long a preamble to his prayer as most people, he would have been forty feet under water before he got through praying for what he wanted. Now, just read a little farther: “And immediately Jesus stretched forth His hand, and caught him, and said unto him: ‘O thou of little faith, wherefore didst thou doubt?’” But I want to pass rapidly over this portion of the Word of God, and get at something which, perhaps, may be of more help to us than any thing here. In the sixteenth chapter of Matthew, twenty-fourth verse, we find that Peter was willing to confess Christ as the Son of the living God. Many men want to be disciples of Christ, but they are not willing to confess Him. “Then said Jesus unto His disciples: ‘If any man will come after Me, let him deny himself and take up his cross and follow Me.” To go home and tell your friends that you want to be a disciple of the Lord Jesus Christ requires much moral courage. But it required more then than it does now, for the Jews said any man who should confess Christ should be cast out of the synagogue. “When Jesus came into the coasts of Cæsarea Philippi, He asked His disciples, saying: ‘Whom do men say that I, the Son of man, am?’ “And they said: ‘Some say that Thou art John the Baptist; some, Elias; and others, Jeremias or one of the prophets.’ “He saith unto them: ‘But whom say ye that I am?’” And Peter--he generally spoke first--speaks out and says: “‘Thou art the Christ, the Son of the living God.’
