John 6:18-21

By now a strong wind was blowing, and the waves on the lake were getting bigger. When they had rowed the boat about three or four miles, they saw Jesus walking on the water, coming toward the boat. The followers were afraid, but Jesus said to them, “It is I. Do not be afraid.” Then they were glad to take him into the boat. At once the boat came to land at the place where they wanted to go.
