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