I often say that there is no human being on earth that can look back at their tribal, ethnic or religious history and not see both sin against others and sin committed by others against their group. That is true at a group level and an individual level.
It is a sin to hold grudge and bitterness. We make ourselves rotten failure faces when we do this. We are to forgive and to love. Jesus said if we fail to forgive those who have sinned against us; He will not forgive us our sins.
So when I see bitter Black racist and White shame faced preachers spitting out resentment and hatred against whites because of the history slavery in the US, I see sin. They do not love and they do not forgive. They also are pretty bad at self examination. As a race, Black Americans and those in Africa have their own dark and deadly track record to confess and seek forgiveness. If the Black tribe came to terms with their own tribal sins, they would heal from carrying hatred and bitterness against whites.
The prevailing black culture is one of coveting. You don’t hear any calls to change this from black pulpits. You hear the opposite.
