28 And Peter answered him, "Lord, if it is you, bid me come to you on the water."

29 He said, "Come." So Peter got out of the boat and walked on the water and came to Jesus;

30 but when he saw the wind, he was afraid, and beginning to sink he cried out, "Lord, save me."

31 Jesus immediately reached out his hand and caught him, saying to him, "O man of little faith, why did you doubt?"
