I believe this is a Biblical pattern we see—after about 400 years of slavery then comes freedom. We can see the parallel in the Biblical narrative and in our own historical one. The Hebrews i.e. the children of Israel were enslaved to the Egyptians for 400 years (see Genesis 15:13, Acts 7:6). So too, this year (2019) is exactly 400 years since the very first slaves were brought to America. A ship, carrying about 20 enslaved Africans, appeared on this horizon, near Point Comfort, a coastal port in the British colony of Virginia.
Though slavery was abolished in 1865 the fight to be free extended well into the 1960s and into the present day. However, this fight has morphed into a mental one. As we fight, “we”, speaking directly about African Americans, to understand our true enemy—the slave master of single, static and liberal thought.
