John 6:28

By the bread which perisheth, is not strictly to be understood bread, but whatsoever is necessary or accommodating to us in this life; all things of this nature are perishing, and perish with the using: nor is all labour as to them forbidden us; for we are to the contrary commanded, In the sweat of our face to eat our bread; and the apostle commandeth, that those that will not labour should not eat; and, Pro 31:27, the good woman is commended for not eating the bread of idleness: but excessive labour for these things is forbidden. So also is a first and greater labour for and seeking after them, than after under which notion also unquestionably cometh whatsoever is necessary by God’s revealed will, that we may have in us the hopes of glory here, and may enter into the actual possession of that glory hereafter. Such as are, first, the knowledge of the gospel; then the believing of it, and the acceptance of that Saviour, and way of salvation, which God hath revealed in it for lost sinners; and that holiness of life which God hath made necessary to it. All which (saith he) I, who am the Son of man, (a name he ordinarily giveth to himself), will give unto you freely. Not that you are to do nothing; no, labour for it; though it be a gift, yet it is a gift upon labour, for all your labour will not procure it; there will be a great deal of free grace seen when you have given all diligence. And Christ must give it; for the Father, in whose hand this life is, hath (as men by their seals use to confirm the commissions they give out to any persons to do any thing for them, and in their name) confirmed Christ as his commissioner, to give out this eternal life to whomsoever he pleaseth.

I. Christ having told them that they must work for the meat he spoke of, must labour for it, they enquire what work they must do, and he answers them, v. 28, 29. 1. Their enquiry was pertinent enough (v. 28): What shall we do, that we may work the works of God? Some understand it as a pert question: "What works of God can we do more and better than those we do in obedience to the law of Moses?" But I rather take it as a humble serious question, showing them to be, at least for the present, in a good mind, and willing to know and do their duty; and I imagine that those who asked this question, How and What (v. 30), and made the request (v. 34), were not the same persons with those that murmured (v. 41, 42), and strove (v. 52), for those are expressly called the Jews, who came out of Judea (for those were strictly called Jews) to cavil, whereas these were of Galilee, and came to be taught. This question here intimates that they were convinced that those who would obtain this everlasting meat, (1.) Must aim to do something great. Those who look high in their expectations, and hope to enjoy the glory of God, must aim high in those endeavours, and study to do the works of God, works which he requires and will accept, works of God, distinguished from the works of worldly men in their worldly pursuits. It is not enough to speak the words of God, but we must do the works of God. (2.) Must be willing to do any thing: What shall we do? Lord, I am ready to do whatever thou shalt appoint, though ever so displeasing to flesh and blood, Acts 9 6. 2. Christ's answer was plain enough (v. 29): This is the work of God that ye believe. Note, (1.) The work of faith is the work of God. They enquire after the works of God (in the plural number), being careful about many things; but Christ directs them to one work, which includes all, the one thing needful: that you believe, which supersedes all the works of the ceremonial law; the work which is necessary to the acceptance of all the other works, and which produces them, for without faith you cannot please God. It is God's work, for it is of his working in us, it subjects the soul to his working on us, and quickens the soul in working for him, (2.) That faith is the work of God which closes with Christ, and relies upon him. It is to believe on him as one whom God hath sent, as God's commissioner in the great affair of peace between God and man, and as such to rest upon him, and resign ourselves to him. See ch. 14 1.

Verses 28-35 Constant exercise of faith in Christ, is the most important and difficult part of the obedience required from us, as sinners seeking salvation. When by his grace we are enabled to live a life of faith in the Son of God, holy tempers follow, and acceptable services may be done. God, even his Father, who gave their fathers that food from heaven to support their natural lives, now gave them the true Bread for the salvation of their souls. Coming to Jesus, and believing on him, signify the same. Christ shows that he is the true Bread; he is to the soul what bread is to the body, nourishes and supports the spiritual life. He is the Bread of God. Bread which the Father gives, which he has made to be the food of our souls. Bread nourishes only by the powers of a living body; but Christ is himself living Bread, and nourishes by his own power. The doctrine of Christ crucified is now as strengthening and comforting to a believer as ever it was. He is the Bread which came down from heaven. It denotes the Divinity of Christ's person and his authority; also, the Divine origin of all the good which flows to us through him. May we with understanding and earnestness say, Lord, evermore give us this Bread.
