Running on Faith Weekday Devotions – Wednesday 7 September 2022:
Jer 31:33b “But this is the covenant…” declares the Lord, “I will put My law within them & on their heart I will write it; & I will be their God, & they shall be My people.”
Jeremiah is the only OT prophet who speaks of the New Covenant, which is the life, death, & resurrection of Jesus Christ (c.f. Mt 26:28).
Ez 36:26 “Moreover, I will give you a new heart & put a new spirit within you; & I will remove the heart of stone from your flesh & give you a heart of flesh.”
Only after Pentecost (Acts 2:1, 10:44) do all believers receive the indwelling Holy Spirit.
2 Cor 3:2–4 “You (Corinth Church) are our (Paul & Timothy) letter, written in our hearts, known & read by all men; being manifested that you are a letter of Christ, cared for by us, written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts (Literally: ‘hearts of flesh’).”
Christians have new hearts!
