Jeremiah 4:3-4
3 For thus saith Jehovah to the men of Judah and to Jerusalem, Break up your fallow ground, and sow not among thorns. 4 Circumcise yourselves to Jehovah, and take away the foreskins of your heart, ye men of Judah and inhabitants of Jerusalem; lest my wrath go forth like fire, and burn so that none can quench it, because of the evil of your doings.

Commentary on Jeremiah 4:3-4
(Read Jeremiah 4:3-4)
An unhumbled heart is like ground untilled. It is ground which may be improved; it is our ground let out to us; but it is fallow; it is over-grown with thorns and weeds, the natural product of the corrupt heart. Let us entreat the Lord to create in us a clean heart, and to renew a right spirit within us; for except a man be born again, he cannot enter into the kingdom of heaven.
