Forsook all - It was not "much" that they left - a couple of small boats and their nets; but it was all they had, even all their living. But this showed their love of Jesus, and their willingness to deny themselves, as "really" as if they had forsaken palaces and gold. All that Jesus asks is that we should leave "all" we have for him; that we should love him "more" than we do whatever friends or property we may possess, and be willing to give them all up when he requires it.

They forsook all, and followed him - God expects this from every person, and especially from those in whose hearts, or in whose behalf, he has wrought a miracle of grace or of providence. Jesus intended to call Peter, James, and John, to become his disciples; and that they might see the propriety and importance of the call, he: -
1st. Teaches in their presence, that they may know his doctrine.
2dly. He Works a Miracle before their eyes, that they might see and be convinced of his power.
3dly. He Calls them to go forth with this doctrine, and through this power, that they might teach the ignorant, and be successful in their work.

And when they had brought their ships to land,.... Both Simon Peter's, and the other in which his partners were, and which were laden with fish:
they forsook all; even all their fish, which they doubtless might have made much money of, and their nets, and their ships, and their servants, and their relations, and friends:
and followed him; Christ; and became his disciples, even all four of them, Peter, Andrew, James, and John.

forsook all--They did this before (Matthew 4:20); now they do it again; and yet after the Crucifixion they are at their boats once more (John 21:3). In such a business this is easily conceivable. After pentecost, however, they appear to have finally abandoned their secular calling.

They forsook all. The four just named. Before this all were disciples; henceforth they follow Jesus personally. These all together cast the gospel net on Pentecost and had a mighty draught.

They forsook all and followed him - They had followed him before, John 1:43, but not so as to forsake all. Till now, they wrought at their ordinary calling.
