31:27-34 The people of God shall become numerous and prosperous. In Heb 8:8,9, this place is quoted as the sum of the covenant of grace made with believers in Jesus Christ. Not, I will give them a new law; for Christ came not to destroy the law, but to fulfil it; but the law shall be written in their hearts by the finger of the Spirit, as formerly written in the tables of stone. The Lord will, by his grace, make his people willing people in the day of his power. All shall know the Lord; all shall be welcome to the knowledge of God, and shall have the means of that knowledge. There shall be an outpouring of the Holy Spirit, at the time the gospel is published. No man shall finally perish, but for his own sins; none, who is willing to accept of Christ's salvation.
But everyone shall die for his own iniquity,.... His own personal iniquity; and not a corporeal death only, but an eternal one, which is the just wages of sin. It seems to intimate, that, after the Babylonish captivity, no public calamity should come upon them for the sins of their fathers and their own jointly, but for their own iniquities singly; so their last destruction by the Romans was for their personal disbelief and rejection of the Messiah; see John 8:24; and the calamities upon them ever since have been for the same reason. Indeed, they imprecated his blood upon them, and upon their children, and so it is; but then, their children are under the power of the same sin of unbelief, and will remain so, until the veil is taken away, and they turn to the Lord; after which it will still be a more clear case that everyone shall die for his own iniquity;
every man that eateth the sour grape, his teeth shall be set on edge; sin, though it may be esteemed a sweet morsel, is a sour grape, and will prove so in the issue; and will give a man as much trouble and disquietude, when he is convinced of the evil of it, or suffers the punishment of it, as when a man's "teeth are set on edge"; and indeed the consequence of it will be weeping, wailing, and gnashing of teeth.
