Jesus sends his disciples ahead in their boat while he prays alone on a mountainside. That night, as the disciples are struggling against strong winds on the sea, Jesus walks toward them on the water. The disciples are terrified until Jesus reassures them it is him. Peter asks to join Jesus and begins walking on water but sinks when he doubts. Jesus saves him and rebukes his lack of faith. The disciples then worship Jesus, acknowledging he is the Son of God.
