Matthew 14:24-31
English Standard Version
Chapter 14
24but the boat by this time was a long way from the land, beaten by the waves, for the wind was against them. 25And in the fourth watch of the night he came to them, walking on the sea. 26But when the disciples saw him walking on the sea, they were terrified, and said, "It is a ghost!" and they cried out in fear. 27But immediately Jesus spoke to them, saying, "Take heart; it is I. Do not be afraid."
28And Peter 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 and walked on the water and came to Jesus.
30But when he saw the wind, he was afraid, and beginning to sink he cried out, "Lord, save me."
31Jesus immediately reached out his hand and took hold of him, saying to him, "O you of little faith, why did you doubt?"
