Matt 14:28-31

28Peter answered him, “Lord, if it is you, command me to come to you on the water.”29He said, “Come.” So Peter got out of the boat, started walking on the water, and came toward Jesus.30But when he noticed the strong wind, he became frightened, and beginning to sink, he cried out, “Lord, save me!”31Jesus immediately reached out his hand and caught him, saying to him, “You of little faith, why did you doubt?”
