Matthew 14:29-32

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? And when they were gone up into the boat, the wind ceased.
