Jesus wasn't the only waterwalker that day:

St. Mathew 14, 18 (NKJ)

28. And Peter answered him and said, Lord, if it be thou, bid me come unto thee on the water.

29. And he said, "Come." And when Peter was come down out of the ship, he walked on the water, to go to Jesus.

30. But when he saw the wind was boisterous, he was afraid; and beginning to sink, he cried, saying, Lord, save me.

31. And immediately Jesus stretched forth his hand, and caught him. And said unto him, O thou of little faith, wherefore didst thou doubt?


18:3 "And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven."
