Matthew 14:26-29

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.
