John 9:24

Give glory to God, before whom thou art speaking, and tell us the truth. It could not be this man who cured thee; for we know he is a sinner, who seduceth the people. (Bible de Vence) — So say our separated brethren, when they derogate from miracles done by saints, pharisaically pretending the glory of God, as if it were not God’s glory when his servants act by his power and virtue. Witness Peter’s shadow, (Acts v.) and Paul’s handkerchiefs that cured diseases, and expelled wicked spirits. (Acts xix. 11, 12.)

(2.) What they said of him, in reply to the man's testimony. Having in vain attempted to invalidate the evidence of the fact, and finding that indeed a notable miracle was wrought, and they could not deny it, they renew their attempt to banter it, and run it down, and do all they can to shake the good opinion the man had of him that opened his eyes, and to convince him that Christ was a bad man (v. 24): Give God the praise, we know that this man is a sinner. Two ways this is understood: [1.] By way of advice, to take heed of ascribing the praise of his cure to a sinful man, but to give it all to God, to whom it was due. Thus, under colour of zeal for the honour of God, they rob Christ of his honour, as those do who will not worship Christ as God, under pretence of zeal for this great truth, that there is but one God to be worshipped; whereas this is his declared will, that all men should honour the Son even as they honour the Father; and in confessing that Christ is Lord we give glory to God the Father. When God makes use of men that are sinners as instruments of good to us, we must give God the glory, for every creature is that to us which he makes it to be; and yet there is gratitude owing to the instruments. It was a good word, Give God the praise, but here it was ill used; and there seems to be this further in it, "This man is a sinner, a bad man, and therefore give the praise so much the more to God, who could work by such an instrument." [2.] By way of adjuration; so some take it. "We know (though thou dost not, who hast but lately come, as it were, into a new world) that this man is a sinner, a great impostor, and cheats the country; this we are sure of, therefore give God praise" (as Joshua said to Achan) "by making an ingenuous confession of the fraud and collusion which we are confident there is in this matter; in God's name, man, tell the truth." Thus is God's name abused in papal inquisitions, when by oaths, ex officio, they extort accusations of themselves from the innocent, and of others from the ignorant. See how basely they speak of the Lord Jesus: We know that this man is a sinner, is a man of sin. In which we may observe, First, Their insolence and pride. They would not have it thought, when they asked the man what he thought of him, that they needed information; nay, they know very well that he is a sinner, and nobody can convince them of the contrary. He had challenged them to their faces (ch. 8 46) to convince him of sin, and they had nothing to say; but now behind his back they speak of him as a malefactor, convicted upon the notorious evidence of the fact. Thus false accusers make up in confidence what is wanting in proof. Secondly, The injury and indignity hereby done to the Lord Jesus. When he became man, he took upon him the form not only of a servant, but of a sinner (Rom 8 3), and passed for a sinner in common with the rest of mankind. Nay, he was represented as a sinner of the first magnitude, a sinner above all men; and, being made sin for us, he despised even this shame.

Verses 24-34 As Christ's mercies are most valued by those who have felt the want of them, that have been blind, and now see; so the most powerful and lasting affections to Christ, arise from actual knowledge of him. In the work of grace in the soul, though we cannot tell when, and how, and by what steps the blessed change was wrought, yet we may take the comfort, if we can say, through grace, Whereas I was blind, now I see. I did live a worldly, sensual life, but, thanks be to God, it is now otherwise with me, ( Ephesians 5:8 ) . The unbelief of those who enjoy the means of knowledge and conviction, is indeed marvellous. All who have felt the power and grace of the Lord Jesus, wonder at the wilfulness of others who reject him. He argues strongly against them, not only that Jesus was not a sinner, but that he was of God. We may each of us know by this, whether we are of God or not. What do we? What do we for God? What do we for our souls? What do we more than others?
