Be willing to forgive others without grudge. No matter how hard they abused you or something, still learn how to forgive. Just like God forgave you on your sins, when you sinned big time or small time, God will openly forgive you. He is glad to forgive you and purify you from all unrighteousness (1 John 1:9).
This is also one way of portraying a Christ-like character. When you want to follow Christ and obey His Word, we must also learn how to forgive. Forgiveness also means releasing everything in His own hands, letting Him take control of the situation. Let it go to God's hands, my friends. Forgive and forget.
