Commentaries:
In verse 3, Paul uses the metaphor of a letter of commendation (verses 1 and 2) to lead into a discussion comparing the Old and New Covenants. When God made the Old Covenant with ancient Israel, Moses wrote the commandments, statutes, and judgments that God had given to him in a book with "ink" (Exodus 24:4). God wrote the Ten Commandments with His own finger on two tablets of stone (Exodus 31:18; 32:15-16). However, Paul points out, under the New Covenant, God has given us His Spirit, enabling us to keep His laws in their spiritual intent. He is now writing His Ten Commandments on our hearts (Hebrews 8:10)!

Have the Ten Commandments Passed Away?
Paul specifically says that the law will be written in the fleshly tables of our heart by the Spirit of the living God! However, the circumcision of the heart is a co-operative effort. God does His part, and we do ours by submitting to Him. Both parts are involved within this process, by which God is enabling us to have the power to sustain a relationship with Him. And that power is given only to the children of promise, the children of God, the church, the remnant, those who are in Christ, those who have received God's Spirit.

The Covenants, Grace, and Law (Part Eleven)
Paul makes it clear that the Spirit God will give us will be the means by which the laws are written on our hearts. "Circumcision of the heart," "writing God's laws on the heart," "conversion," and "changing" essentially describe the same thing.
