Christianity is all about forgiveness; not resentment. Forgiveness is freedom; walking free in Christ’s love out from the darkness of injustice and evil.
Tribal revenge, resentment and hatred is sin; walking in the opposite of Christ - evil. You can tell by the fruit born through forgiveness - peace, prosperity and love - versus that born by tribalism - war, poverty and hate on an individual and societal level.
Can’t we simply dismiss the premises here? There is nothing for any living human to forgive. All the people who enslaved, and who were enslaved, are dead.
Amen.
Christ warned us these days would come.
