Matthew 14:24-31 New International Version (NIV)

²⁴ and the boat was already a considerable distance from land, buffeted by the waves because the wind was against it.

²⁵ Shortly before dawn Jesus went out to them, walking on the lake. ²⁶ When the disciples saw him walking on the lake, they were terrified. “It’s a ghost,” they said, and cried out in fear.

²⁷ But Jesus immediately said to them: “Take courage! It is I. Don’t be afraid.”

²⁸ “Lord, if it’s you,” Peter replied, “tell me to come to you on the water.”

²⁹ “Come,” he said.

Then Peter got down out of the boat, walked on the water and came toward Jesus. ³⁰ But when he saw the wind, he was afraid and, beginning to sink, cried out, “Lord, save me!”

³¹ Immediately Jesus reached out his hand and caught him. “You of little faith,” he said, “why did you doubt?”
