Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do ye. Colossians 3:13 KJV
This is the formula for unity and peace.
Forbearing one another requires us to esteem one another higher than ourselves.
Forgiveness demands that we recognize God as the only righteous Judge.
Walking in love is manifest by forgiving any, and all, hurtful words or deeds to the point they no longer torment you.
