Commentary on the Gospel According to John John Calvin
Commentary on John of Tiberias, according to the Hebrew custom, is called the Sea of Tiberias.
3. I am going to fish. That Peter gave his attention to fishing, ought not to be regarded as inconsistent with his office. By breathing on him, Jesus had ordained him to be an Apostle, as we saw a little before; but he abstained from the exercise of the apostleship for a short time, till he should be clothed with new power. For he had not yet been enjoined to appear in public for the discharge of his office of teaching, but had only been reminded of his future calling, that he and the others might understand that they had not in vain been chosen from the beginning. Meanwhile, they do what they were accustomed to do, and what belonged to men in private life. It is true that Paul, in the midst of his employment as a preacher, gained the support of his life by his own hands, but it was for a different reason; for his time was so arranged, that the labors of his hands did not withdraw him from teaching. Peter and his companions, on the other hand, give themselves up entirely to fishing, because they are not hindered from doing so by any public employment.
And that night they caught nothing. God permitted them to toil to no purpose during the whole night, in order to prove the truth of the miracle; for if they had caught any thing 558 what followed immediately afterwards would not have so clearly manifested the power of Christ, but when, after having toiled ineffectually during the whole night, they are suddenly favored with a large take of fishes, they have good reason for acknowledging the goodness of the Lord. In the same manner, also, God often tries believers, that he may lead them the more highly to value his blessing. If we were always prosperous, whenever we put our hand to labor, scarcely any man would attribute to the blessing of God the success of his exertions, all would boast of their industry, and would kiss their hands. But when they sometimes labor and torment themselves without any advantage, if they happen afterwards to succeed better, they are constrained to acknowledge something out of the ordinary course; and the consequence is, that they begin to ascribe to the goodness of God the praise of their prosperity and success.
6. Cast the net on the right side of the ship. Christ does not command with authority and power as Master and Lord, but gives advice like one of the people; and the disciples, being at a loss what to do, readily obey him, though they did not know who he was. If, before the first casting of the net, any thing of this sort had been said to them, they would not have so quickly obeyed. I mention this, that no one may wonder that they were so submissive, for they had already been worn out by long and useless toil. Yet it was no small proof of patience and perseverance, that, though they had labored unsuccessfully during the whole night, they continue their toil after the return of daylight. And, indeed, if we wish to allow an opportunity for the blessing of God to descend on us, we ought constantly to expect it; for nothing can be more unreasonable than to withdraw the hand immediately
558"S'ils eussen, fait quelque prinse de poissons;" — "if they had had any take of fishes."
