Matthew 14:22-31

And straightway he constrained the disciples to enter into the boat, and to go before him unto the other side, till he should send the multitudes away. And after he had sent the multitudes away, he went up into the mountain apart to pray: and when even was come, he was there alone. But the boat was now in the midst of the sea, distressed by the waves; for the wind was contrary. And in the fourth watch of the night he came unto them, walking upon the sea. And when the disciples saw him walking on the sea, they were troubled, saying, It is a ghost; and they cried out for fear. But straightway Jesus spake unto them, saying, Be of good cheer; it is I; be not afraid. And Peter answered him and said, Lord, if it be thou, bid me come unto thee upon the waters. And he said, Come. And Peter went down from the boat, and walked upon the waters to come to Jesus. But when he saw the wind, he was afraid; and beginning to sink, he cried out, saying, Lord, save me. And immediately Jesus stretched forth his hand, and took hold of him, and saith unto him, O thou of little faith, wherefore didst thou doubt?
