Matthew 14:28-31

And Peter answered him and said, “Lord, if it is you, command me to come to you on the water!” So he said, “Come!” And getting out of the boat, Peter walked on the water and came toward Jesus. But when he saw the strong wind, he was afraid. And beginning to sink, he cried out, saying, “Lord, save me!” And immediately Jesus extended his hand and caught him and said to him, “You of little faith! Why did you doubt?”
