Colossians 3:12-14 says:
12God has chosen you and made you his holy people. He loves you. So always do these things: Show mercy to people; be kind, humble, gentle, and patient. 13Don't be angry with each other, but forgive each other. If another person does something wrong against you, then forgive that person. Forgive other people because the Lord forgave you. (Easy-to-Read Version)
King James Version: 12Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, humbleness of mind, meekness, longsuffering; 13Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do ye.
