Jeremiah 4:3,4

For thus saith the Lord The prophet now addresses himself to the inhabitants of Judah and Jerusalem, and exhorts them to repentance and reformation in metaphorical language. Break up your fallow ground, &c. That is, purge and purify the field of your hearts, by godly sorrow for your sins, and hatred to them; prepare your hearts for receiving the seed of the divine word, by making them soft, tender, and pliable, fit to believe and obey it. And sow not among thorns Eradicate the lusts and vices, the corrupt principles and dispositions, habits, and practices, which, unless rooted out, will effectually choke the good seed of truth and grace, and prevent the growth of piety and virtue in your souls. Circumcise yourselves to the Lord Put away your corruptions; mortify your vicious inclinations and passions: the same thing with the former, expressed in other words. Take away the foreskin of your heart Let your repentance and renovation be inward in your soul and spirit, and not merely outward in your flesh; lest my fury come forth like fire Which it is now ready to do, as that fire which came forth from the Lord, and consumed the sacrifices; and burn that none can quench it Which wrath is not only fierce and consuming like fire, but unquenchable; because of the evil of your doings Which is the thing that kindles the fire of God's wrath against us. Observe, reader, that which is to be dreaded by us more than any thing else, in time or eternity, is the wrath of God kindled against us by the evil of our doings, for it is the spring and bitterness of all present miseries, and will be the quintessence and perfection of everlasting misery. And the consideration of the imminent danger we are in of falling and perishing under this wrath, should awaken us with all possible care to sanctify ourselves to God's glory, and to see to it that we be sanctified by his grace.
