Matthew 14:28-31

Peter replied, “Lord, if it really is you, tell me to come to you on the water.” “Come on!” Jesus said. Peter then got out of the boat and started walking on the water toward him. But when Peter saw how strong the wind was, he was afraid and started sinking. “Save me, Lord!” he shouted. At once, Jesus reached out his hand. He helped Peter up and said, “You surely don't have much faith. Why do you doubt?”
