Matthew 14:29-31

Peter went down from the boat, and walked on the waters to come to Jesus. ³⁰But when he saw that the wind was strong, he was afraid, and beginning to sink, he cried out, saying, "Lord, save me!" ³¹Immediately Jesus stretched forth his hand, and took hold of him, and said to him, "You of little faith, why did you doubt?"
