With remarkable trust Peter climbed over the side of the boat and began walking on the water. Hebrews , too, in obedience to Jesus" command, was able to fulfill man"s destiny by subduing the sea. He was doing well until he became more concerned about the waves than about Jesus. "Seeing the wind" is a figure of speech (synecdoche) for seeing the storm. His distressing circumstances distracted his attention and weakened his faith in Jesus. Jesus rebuked him for his weak faith even though it was stronger than that of the other disciples who remained in the boat. Jesus used this rebuke to help Peter and the other disciples see that consistent confidence in Himself was absolutely necessary. Peter became both a good example and a bad one. Jesus rescued him as God had rescued many others from watery graves (cf. Psalm 18:16; Psalm 69:1-3; Psalm 144:7; Jonah 2:10). [source][source][source]
