Therefore, as the elect of God, holy and beloved, put on tender mercies, kindness, humility, meekness, longsuffering; bearing with one another, and forgiving one another, if anyone has a complaint against another; even as Christ forgave you, so you also must do. But above all these things put on love, which is the bond of perfection. (Colossians 3:12-14 NKJV)
God forgives every negative action that we do to one another. He is a forgiving God and he loves us so much that he took physics and mental pain just for us. If God can forgive all the people that hurt Him, we can forgive someone that has hurt us. He had thousands of people against him and hurt him.. We are not going through anything compared to God. We need to show our love to one another because that's what God asks of us. The showing of love is a sign of perfection in God's eyes.
