4:18-22 When Christ began to preach, he began to gather disciples, who should be hearers, and afterwards preachers of his doctrine, who should be witnesses of his miracles, and afterwards testify concerning them. He went not to Herod's court, not to Jerusalem, among the chief priests and the elders, but to the sea of Galilee, among the fishermen. The same power which called Peter and Andrew, could have wrought upon Annas and Caiaphas, for with God nothing is impossible. But Christ chooses the foolish things of the world to confound the wise. Diligence in an honest calling is pleasing to Christ, and it is no hinderance to a holy life. Idle people are more open to the temptations of Satan than to the calls of God. It is a happy and hopeful thing to see children careful of their parents, and dutiful. When Christ comes, it is good to be found doing. Am I in Christ? is a very needful question to ask ourselves; and, next to that, Am I in my calling? They had followed Christ before, as common disciples, Joh 1:37; now they must leave their calling. Those who would follow Christ aright, must, at his command, leave all things to follow him, must be ready to part with them. This instance of the power of the Lord Jesus encourages us to depend upon his grace. He speaks, and it is done.
19. And he saith unto them, Follow me—rather, as the same expression is rendered in Mark, "Come ye after Me" (Mr 1:17).
and I will make you fishers of men—raising them from a lower to a higher fishing, as David was from a lower to a higher feeding (Ps 78:70-72).
