Ok, so when we think of righteous indignation or anger...we must be careful to do this spiritually and with a spiritual focus...not letting the carnal mind seep in for any consideration of the matter. Otherwise, we would be instantly going carnal and totally changing the definition of such anger and perspective. This righteous indignation must be Yhvh's Himself and not our own for He is in us and we have His mind and heart. All things are done unto God, even becoming angry. But even the anger must be a loving anger for God is love and we are to become love and love our brothers as ourselves.
Make sense?
