When sinned against, it’s easy to only see only the horizontal significance of what occurred. “This is about me and the one who hurt me!” we argue. But for those who worship God, forgiveness is an act of worship. This is primarily about God and secondarily about me. When we forgive, we “let go of” instead of “holding on to” or “holding against.”
Forgiveness is an act of releasing to God the hurtful actions and consequences of the wrong done to us.
