As Christ forgave you, so you also must do. 

There was a certain creditor who had two debtors. One owed five hundred denarii, and the other fifty. And when they had nothing with which to repay, he freely forgave them both. § I forgave you all that debt … Should you not also have had compassion on your fellow servant, just as I had pity on you?And whenever you stand praying, if you have anything against anyone, forgive him, that your Father in heaven may also forgive you your trespasses. But if you do not forgive, neither will your Father in heaven forgive your trespasses. § 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.“Lord, how often shall my brother sin against me, and I forgive him? Up to seven times?” Jesus said to him, “I do not say to you, up to seven times, but up to seventy times seven.”Love … is the bond of perfection.
