And of course we have to keep in mind that today - black Americans have far more opportunity to educate and uplift themselves than blacks currently living in most areas in Africa. As horrible as slavery was, the American descendants of slaves are better off than the ones than many that stayed in Africa.
I do think that is what Michelle Obama was trying to say - but we can all do without the constant whining of how bad it was. It was terrible, it’s over - move on.
There’s a gracious God that allowed the evils to happen. But nobody has clean hands in this mortal coil. What we call original sin isn’t a convenient fiction; it’s real. We don’t even know how much of God’s grace we threw away until we encounter it once more.
Anyhow... if we deal with the evils head on as best we can as they come, we will find that our lives have been tailored by God to shed sin and regain righteousness.
