John 6:40

This is the will of him that sent me - Lest they should take a wrong meaning out of his words, as many have done since, he tells them that, far from any person being excluded from his mercy, it was the will of God that every one who saw him might believe and be saved. The power, without which they could not believe, he freely gave them; but the use of that power was their own. God gives the grace of repentance and faith to every man; but he neither repents nor believes for any man. Each must repent for his own sins, and believe in the Lord Jesus, through the grace given, or perish.

Every one which seeth the Son, and believeth on him - It was not sufficient to see him and hear him, but it was necessary, also, to believe on him. Many of the Jews had seen him, but few believed on him. Jesus had said in the previous verse that all that the Father had given him should be saved. But he never left a doctrine so that men must misunderstand it. Lest it should be supposed that if a man was given to him this was all that was needful, and lest anyone should say, "If I am to be saved I shall be, and my efforts will be useless," he states here that it is necessary that a man should believe on him. This would be the evidence that he was given to God, and this would be evidence conclusive that he would be saved. If this explanation of the Saviour had always been attended to, the doctrine of election would not have been abused as it has been. Sinners would not sit down in unconcern, saying that if they are given to Christ all will be well. They would have arisen like the prodigal, and would have gone to God; and, having believed on the Saviour, they would then have had evidence that they were given to him - the evidence resulting from an humble, penitent, believing heart - and then they might rejoice in the assurance that Jesus would lose none that were given to him, but would raise it up at the last day. All the doctrines of Jesus, as he preached them, are safe, and pure, and consistent; as men preach them, they are, unhappily, often inconsistent and open to objection, and are either fitted to produce despair on the one hand, or presumptuous self-confidence on the ether. Jesus teaches men to strive to enter heaven, as if they could do the work themselves; and yet to depend on the help of God, and give the glory to him, as if he had done it all.

6:40 Here is the sum of the three foregoing verses. This is the will of him that sent me - This is the whole of what I have said: this is the eternal, unchangeable will of God. Every one who truly believeth, shall have everlasting life. Every one that seeth and believeth - The Jews saw, and yet believed not. And I will raise him up - As this is the will of him that sent me, I will perform it effectually.
