Rhiannon knows that her very appearance [white, Welsh] reminds many Africans of rejection and unjust dominance, but instead of disclaiming all association with the colonial past by such statements as … "It was all in a past generation" or "My people have been oppressed too", she volunteers to stand in the gap as an intercessor. The Bible reveals that God is looking for such people. Not just people who will stand in the gap before Him, but people who will repair the breeches in human relationships. God does not put guilt on the intercessor. We are not individually guilty for what our group or our parents did, but He is waiting for a "royal priesthood," which is the redeemed in Christ, to openly convess the truth of a matter before Him and before people, just as the ancient Hebrew priests did once over the sins of Israel. You see, it is very difficult to forgive if you have never heard an open acknowledgment of the injustices that wounded you or your people. On the other hand, such grace for forgiveness is released when we are asked for forgiveness by those who identify themselves in some way with the identity of those who contributed to our suffering. Identification, as used in this sense, signifies the act of consciously including oneself within an identifiable category of human beings.
