29 Jesus answered them, "This is the work of God, that you believe in him whom he has sent."

The work of God is this. They had spoken of works Christ reminds them of one work, that is, faith; by which he means that all that men undertake without faith is vain and useless, but that faith alone is sufficient, because this alone does God require from us, that we believe For there is here an implied contrast between faith and the works and efforts of men; as if he had said, Men toil to no purpose, when they endeavor to please God without faith, because, by running, as it were, out of the course, they do not advance towards the goal. This is a remarkable passage, showing that, though men torment themselves wretchedly throughout their whole life, still they lose their pains, if they have not faith in Christ as the rule of their life. Those who infer from this passage that faith is the gift of God are mistaken; for Christ does not now show what God produces in us, but what he wishes and requires from us. But we may think it strange that God approves of nothing but faith alone; for the love of our neighbor ought not to be despised, and the other exercises of religion do not lose their place and honor. So then, though faith may hold the highest rank, still other works are not superfluous. The reply is easy; for faith does not exclude either the love of our neighbor or any other good work, because it contains them all within itself. Faith is called the only work of God, because by means of it we possess Christ, and thus become the sons of God, so that he governs us by his Spirit. So then, because Christ does not separate faith from its fruits, we need not wonder if he make it to be the first and the last. [1] That you believe in him whom he hath sent. What is the import of the word believe, we have explained under the Third Chapter. It ought always to be remembered that, in order to have a full perception of the power of faith, we must understand what Christ is, in whom we believe, and why he was given to us by the Father. It is idle sophistry, under the pretext of this passage, to maintain that we are justified by works, if faith justifies, because it is likewise called a work First, it is plain enough that Christ does not speak with strict accuracy, when he calls faith a work, just as Paul makes a comparison between the law of faith and the law of works, (Romans 3:27.) Secondly, when we affirm that men are not justified by works, we mean works by the merit of which men may obtain favor with God. Now faith brings nothing to God, but, on the contrary, places man before God as empty and poor, that he may be filled with Christ and with his grace. It is, therefore, if we may be allowed the expression, a passive work, to which no reward can be paid, and it bestows on man no other righteousness than that which he receives from Christ.
1 - "Proram et puppim," literally, "stem and stern," a Latin idiom for the whole. The Author's French version (ed. 1558) renders the clause, "il ne se faut point esbahir s'il constitue en elle la fin et le commencement;" -- "we must not be astonished if he makes it to be the end and the beginning;" and in ed. 1564, it runs thus, "ce n'est pas merveille que la foy est tout ce que Dieu requiert;" -- "it is not wonderful that faith is all that God requires."
This is the work of God - This is the thing that will be acceptable to God, or which you are to do in order to be saved. Jesus did not tell them they had nothing to do, or that they were to sit down and wait, but that there was a work to perform, and that was a duty that was imperative. It was to believe on the Messiah. This is the work which sinners are to do; and doing this they will be saved, for Christ is the end of the law for righteousness to everyone that believeth, Romans 10:4.
This is the work of God, that ye believe - There is nothing you can be employed in more acceptable to God than in yielding to the evidence set before you, and acknowledging me as your Messiah and the Savior of a lost world.
(5) Jesus answered and said unto them, (g) This is the work of God, that ye believe on him whom he hath sent.
(5) Men torment themselves in vain when they try to please God without faith.
(g) That is, this is the work that God requires, that you believe in me, and therefore he calls them back to faith.
Jesus answered and said unto them, this is the work of God,.... The main and principal one, and which is well pleasing in his sight; and without which it is impossible to please him; and without which no work whatever is a good work; and this is of the operation of God, which he himself works in men; it is not of themselves, it is the pure gift of God:
that ye believe on him whom he hath sent; there are other works which are well pleasing to God, when rightly performed, but faith is the chief work, and others are only acceptable when done in the faith of Christ. This, as a principle, is purely God's work; as it is an act, or as it is exercised under the influence of divine grace, it is man's act: "that ye believe"; the object of it is Christ, as sent by the Father, as the Mediator between God and men, as appointed by him to be the Saviour and Redeemer; and believing in Christ, is believing in God that sent him. The Jews reduce all the six hundred and thirteen precepts of the law, for so many they say there are, to this one, "the just shall live by his faith", Habakkuk 2:4. (e).
(e) T. Bab. Maccot, fol. 23. 2. & 24. 1.
This is the work of God--That lies at the threshold of all acceptable obedience, being not only the prerequisite to it, but the proper spring of it--in that sense, the work of works, emphatically "the work of God."
This is the work of God, that ye believe on him whom he hath sent. They are startled by hearing that to please God the first requirement is faith in Christ. This is "the work of God" that pleases him. "Without faith it is impossible to please God." It is not works, but one work, that is required, a faith that would enable them to lay hold upon him who is the Bread of Life. From such faith would spring a Christlike life.
This is the work of God - The work most pleasing to God, and the foundation of all others: that ye believe - He expresses it first properly, afterward figuratively.
