A miraculous act performed by Jesus, according to the Gospels. They record that Jesus walked on the Sea of Galilee to rejoin his disciples, who had departed ahead of him in a ship. When he reached the ship, the winds that had been blowing stopped, and the disciples worshiped him as the true son of God.
Note: Figuratively, to “walk on water” is to perform an impossible or godlike task: “When I told him the project had to be done by Tuesday, he made me feel as though I were asking him to walk on water.”
