Matthew 14:28-31    King James Version

28 And Peter answered him and said, Lord, if it be thou, bid me come unto thee on the water.

29 And he said, Come. And when Peter was come down out of the ship, he walked on the water, to go to Jesus.

30 But when he saw the wind boisterous, he was afraid; and beginning to sink, he cried, saying, Lord, save me.

31 And immediately Jesus stretched forth his hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt?
