John Calvin Commentary Matthew 21:43

"Therefore say I unto you, The kingdom of God shall be taken away from you, and shall be given to a nation bringing forth the fruits thereof." — Matthew 21:43 (ASV)

Therefore I say to you. Until now, Christ directed His discourse to rulers and governors, but in the presence of the people. Now, however, He addresses the people themselves in the same manner, and not without reason, for they had been the companions and assistants of the priests and scribes in hindering the grace of God.

It was from the priests, no doubt, that the evil arose; but the people, on account of their sins, had already deserved to have such corrupt and degenerate pastors. Besides, the whole body was infected, as it were, with a similar malice to resist God.

This is the reason why Christ denounces the dreadful vengeance of God against all indiscriminately. For as the priests were inflated with the desire of holding the highest power, so the rest of the people gloried on the ground of having been adopted. Christ now declares that God was not bound to them and, therefore, that He will convey to another the honor of which they had rendered themselves unworthy.

And this, no doubt, was once spoken to them, but it was written for the sake of all of us. If God chooses us to be His people, we should not become presumptuous through a vain and wicked confidence in the flesh, but should endeavor, on our part, to perform the duties which He enjoins on His children.

For if He spared not the natural branches, (Romans 11:21).

What will He do with those who were engrafted? The Jews thought that the kingdom of God dwelt among them by hereditary right, and therefore they adhered obstinately to their vices. We have unexpectedly come into their place contrary to nature, and therefore the kingdom of God is much less bound to us, if it is not rooted in true godliness.

Now, just as our minds ought to be struck with terror by Christ’s threatening that those who have profaned the kingdom of God will be deprived of it, so the perpetuity of that kingdom, which is here described, may afford comfort to all the godly.

For by these words Christ assures us that, though the ungodly destroyed the worship of God among themselves, they would never cause the name of Christ to be abolished or true religion to perish. For God, in whose hand are all the ends of the earth, will find elsewhere a dwelling and habitation for His kingdom.

We ought also to learn from this passage that the Gospel is not preached in order that it may lie barren and inoperative, but in order that it may yield fruit.
