I will put my laws on their hearts and write them on their minds. The book of Hebrews quotes Jeremiah 31 here, the promise of the New Covenant. "Law on the heart" does not mean a rulebook but rather: God's nature becomes part of you. You no longer need external regulations because the Spirit dwells in you.
Your mind may still be accustomed to distance, a relic of religious conditioning. But in the New Covenant, closeness to God is not a special privilege. You belong. The Spirit of God makes sonship real in your heart.
Today you may understand closeness not as achievement but as a fact of your standing.
