Forgiveness benefits you, not necessarily the other person. It doesn’t say you condone what happened, it simply says that your releasing negativity’s hold on you….give it to God who is infinitely more capable of dealing with it than you are.
Make allowance for each other’s faults, and forgive anyone who offends you. Remember, the Lord forgave you, so you must forgive others.
Colossians 3:13 NLT
