The solution to our stubborn hearts is a circumcised heart. God commands His people to acquire something which, on their own, they simply cannot do. We cannot “circumcise” our hearts. We cannot remove the encrusted wickedness that corrupts our souls and keeps us from taking the will of God, as revealed in His Law, as our priority in life (Heb. 9.8, 14). The heart is deceitful and desperately wicked: who can know it (Jer. 17.9)? And if we cannot know it, how shall we be able to repair it by removing all that wickedness which keeps us from loving God and His Law?
In order to bless us with His “good”, God requires of us something we cannot accomplish: He requires that we “circumcise” our hearts. And what God requires of us, He will hold us accountable to perform (Gen. 4.6-12).
Here again, the grace of the Law is evident. For what God requires of His people, He promises to perform on their behalf (cf. Deut. 30.1-10). God promised to circumcise the hearts of His people so that they would be able to keep His Law and, thereby, know the blessings of His covenant. He is powerful to conceive the Law and to require its obedience; He is also powerful to enable His people to love and walk in it.
Jeremiah and Ezekiel assign the fulfillment of the promise of Deuteronomy 30.1-10 to the time of the New Covenant (Jer. 31.31-34; Ezek. 36.26, 27). All those, therefore, who have come to faith in Jesus Christ have received a new heart, a clean heart, and the indwelling Spirit of God. And all who have that Spirit in them will have hearts formed by the Spirit to know and obey the Law of God, unto their good.

The Law of God is the soil which, fertilized by the rest of God’s Word and watered by His Spirit, brings forth the fruit of Christian life.
