During the fourth watch of the night, Jesus went out to them, walking on the lake. When the disciples saw him walking on the lake, they were terrified. “It’s a ghost,” they said and cried out in fear. But Jesus immediately said to them: “Take courage! It is I. Don’t be afraid.” “Lord, if it’s you,” Peter replied, “tell me to come to you on the water.” “Come,” he said. Then Peter got out of the boat, walked on water, and came toward Jesus. (Matt. 14:25-29 NIV)
