I agree to some of that. But I'm seeing a sea change among black churches here in Alabama. More and more you see black churches with a Sav-A-Life house (pro-life place for pregnant moms). Also I have more blacks come to me telling me that George Floyd ain't their hero, that they're Christian first and black second.
I go to a majority black church set up by whites but in a black neighborhood. Like many majority white churches in my area, we've had a lot of blacks join because they were tired of the regular blame-the-whitey message from the black pulpits. They wanted their families to be part of a love-God and love-others type church. This grassroots movement of real Christianity blacks has grown enough that the emptying black churches have taken notice and many of them have cleaned up their act. I'm cautiously optimistic that we're seeing a spiritual awakening among blacks like their ancestors had during segregation and their ancestors had during slavery.
I tell them all the time that this generation is the one time black America doesn't have to wait on white America to also have a spiritual awakening (so that whites would abolish slavery and later whites end segregation). This time the spiritual awakening among blacks is enough to get what they need (to end all the effects hedonism does to black families).
praying you are correct and the revival will come for US all
