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?
Micah 6:8 - He has showed you, O man, what is good. And what does the LORD require of you? To act justly and to love mercy and to walk humbly with your God
Immense riches are seldom possessed by leaders of countries or corporations without the oppression of their citizens, employees or investors. Immense riches are seldom gained without the willingness to rape and plunder the earth. Unlike their neighbours, and unlike our modern industrial societies, people in ancient Israel (those who atheists call dim-witted bronze-age goat herders) were to make sure they did nothing to take advantage of each other.
Peace, Mercy and Justice were then and are today to be the hallmark of God's people.
