You know how atheists rarely venture outside of the Old Testament lest they run into teachings of Jesus that convict them of a deep need for forgiveness? And you know how atheists accuse Christians of cherry-picking verses to make our case? Do you think atheists ever do the same thing? Now atheists incorrectly associate Southern U.S. Slavery with the safety net slavery of early Israel. That is why you will never see or hear an atheist ranting about this?
Ezekiel 36:26-27 - I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh. And I will put my Spirit in you and move you to follow my decrees and be careful to keep my laws.
