The incident recorded here is obviously not the first time Jesus had been in contact with the men whom He called to be His disciples. Luke already had stated that Jesus had healed Simon’s mother-in-law which denotes previous contact with Simon and Andrew. This seems to be at least the third time Jesus had contact with these men
Peter willingly let the Lord borrow his boat and pushed it out a little from the land. The Lord sat down and began to teach the people from this unconventional platform.
The acoustical properties of this area are remarkable. The still water acts as a sounding board, a loudspeaker. It picks up a speaker’s voice and throws it up the beach and the hillside so that everyone can hear what is being said even when it is spoken in a conversational tone of voice. The Lord did not have to raise His voice to be heard by one and all.
We can picture Peter, pleased and proud that the great preacher Himself should be sitting there in his boat, His voice ringing out to one and all. Peter’s companions were nearby, busily mending their nets with their hands while listening to Jesus with all of their ears (5:2
He summoned his partners, who by now had launched the other boat, and they drew alongside. Peter was still quite sure that he could handle things. He pulled on the net—and it broke. Still confident of his ability to handle things, Peter headed for the shore with this spectacular catch on board at last. Then the ship began to sink! That was the end of his self-will. He fell at Jesus’ knees, saying, “Depart from me; for I am a sinful man, O Lord” (5:8). The Lord had said nothing at all about sin!
From then on, too, their ministry was to be spiritual. Perhaps the Lord’s teaching that day had prepared their souls for that truth. One way or another, “they forsook all, and followed him” (5:11).
