Verse 20. - And they straightway left their nets. (For their leaving everything Wetstein, on ver. 19, compares Epictetus, 12, Ἐάν δὲ κυβερνήτης καλέσῃ τρέχε ἐπὶ τὸ πλοῖον ἀφεὶς ἐκεῖνα πάντα μηδὲν ἐπιστρεφόμενος, "If the steersman call, run to the ship, leaving all those things, without regarding anything.") The Rheims Version, with its love of archaisms, has, "But they incontinent, leaving the nettes, followed him."

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.And they straightway left their nets,.... That is, as soon as he had called them, they left their worldly employment, and followed him; they gave up themselves to his service, and became his disciples; they not only left their "nets", but their fishing boats, and fishing trade, and all that belonged to it, even all their substance; and also their relations, friends, and acquaintance, see Matthew 19:27 which shows what a mighty power went along with the words and call of Christ; and what a ready, cheerful, and voluntary subjection this produces, wherever it takes place.
