When evening came, his disciples went down to the sea, got into a boat, and started across the sea to Capernaum. It was now dark, and Jesus had not yet come to them. The sea became rough because a strong wind was blowing. When they had rowed about three or four miles, they saw Jesus walking on the sea and coming near the boat, and they were terrified. But he said to them, "It is I; do not be afraid." Then they wanted to take him into the boat, John 6:16-21a
We would rather have holiness contained in the boat with us than to see it loose and walking the waves of the sea.
