Commentary on the Gospel According to John John Calvin
John Calvin they were not wealthy enough to entertain so many people.
10. Make the men sit down. That the disciples were not sooner prepared to cherish the hope which their Master held out, and did not remember to ascribe to his power all that was proper, was a degree of stupidity worthy of blame; but no small praise is due to their cheerful obedience in now complying with his injunction, though they know not what is his intention, or what advantage they will derive from what they are doing. The same readiness to obey is manifested by the people; for, while they are uncertain about the result, they all sit down as soon as a single word of command has been pronounced. And this is the trial of true faith, when God commands men to walk, as it were, in darkness. For this purpose let us learn not to be wise in ourselves, but, amidst great confusion, still to hope for a prosperous issue, when we follow the guidance of God, who never disappoints his own people.
11. After having given thanks. Christ has oftener than once instructed us by his example that, whenever we take food, we ought to begin with prayer. For those things which God has appointed for our use, being evidences of his infinite goodness and fatherly love towards us, call on us to offer praise to Him; and thanksgiving, as Paul informs us, is a kind of solemn sanctification, by means of which the use of them begins to be pure to us, (1 Timothy 4:4.) Hence it follows, that they who swallow them down without thinking of God, are guilty of sacrilege, and of profaning the gifts of God. And this instruction is the more worthy of attention, because we daily see a great part of the world feeding themselves like brute beasts. When Christ determined that the bread given to the disciples should grow among their hands, we are taught by it that God blesses our labor when we are serviceable to each other.
Let us now sum up the meaning of the whole miracle. It has this in common with the other miracles, that Christ displayed in it his Divine power in union with beneficence, It is also a confirmation to us of that statement by which he exhorts us to seek the kingdom of God, promising that all other things shall be added to us, (Matthew 6:33.) For if he took care of those who were led to him only by a sudden impulse, how would he desert us, if we seek him with a firm and steady purpose? True, indeed, he will sometimes allow his own people, as I have said, to suffer hunger; but he will never deprive them of his aid; and, in the meantime, he has very good reasons for not assisting us till matters come to an extremity.
Besides, Christ plainly showed that he not only bestows spiritual life on the world, but that his Father commanded him also to nourish the body. For abundance of all blessings is committed to his hand, that, as a channel, he may convey them to us; though I speak incorrectly by calling him a channel, for he is rather the living fountain flowing from the eternal Father. Accordingly, Paul prays that all blessings may come to us from God the Father, and from the Lord Jesus Christ, in common, (1 Corinthians 1:3;)
