True forgiveness is not only for your offenders, you have to forgive yourself as well. Looking inside yourself to see how you reacted to others. Stop trying to convince yourself that you were justified," because after all someone did so & so and hurt my feelings, made me mad, etc." Just for one moment, STOP....
Now, can you picture Jesus saying that? Of course not!
If we are supposed to Become Christ like" we have to forgive one another. The next time you are about to react in the flesh, picture Jesus reacting that way toward you when your behavior is not acceptable.
Matthew 18:21-22 (KJV) 21 Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times? 22 Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven.
