Matthew 14:28

Peter answered. Only Matthew records the embarrassing and almost fatal experience of Peter upon this occasion. Peter had been in charge of the fishing business in which at least four of the disciples were engaged before they became disciples (see on Mark 3:16), and it was therefore probably natural to him and to the others that he should be spokesman for the entire group. His natural mood of leadership, now as upon so many other occasions, led to overconfidence and to an impulsive and injudicious course of action (see Matt. 16:21-23; 17:4; 26:33-35, 69-75; John 18:10, 11; 20:2-6; Gal. 2:11-14; for a character sketch of Peter see on Mark 3:16).

If it be thou. Peter had no doubt in his mind, for otherwise he would hardly have stepped out of the boat onto the wind-tossed waves.

Bid me come. Peter was ready to do the bidding of Jesus, but would not proceed until he had the assurance that Jesus approved.
