Someone has hurt you and this rage just builds up.Forgiveing someone can be one of the hardist things to do for some people. I accepted Jesus as the lord of my life but sometimes i just felt like i still had something missing. Later i realived was one of the biggest commandment Jesus told us TO LOVE EVERYONE EVEN YOUR ENEMY. There was a person if my life who i really never got along with and just lots of stuff happened that i dont want to reviel but after the years went by i had a hatred inside of me. The thing was this person was part of my family. It always hurt me untill one day i really had to do something about it. I came open about it and confronted this peron but before God took control. I totaly humbled myself before him and asked him to get this hatred out of me and help me forgive just like he forgives. Then God’s awsome presence came into the room. Then i relised why Jesus always preached about love. Hatred is so bad and will eat you from the inside but God’s awsome love will set you free. Since that time i never hold a grudge agains anyone and God has givin me such a huge heart for everyone.
I belive that when you forgive someone and start loving them you can beat the evil’s of this world. When he dont forgive someone and keep thinking negative about them all we do is hurt ourselfes and our relationship with Jesus. Jesus forgives us no matter what so whats why us as his followers have to be like him and forgive. One person that really made me belive this was actully a person i saw on tv. I was flipping through channles and this lady was there. Her daughter was murdered by this person and the first thing she thought was she forgave that person. I couldent belive it. Later i though of it and well if this lady forigve a man who murdered her daughter i can forgive anyone to. Since that time im not the same person i was and now belive that with love you can conquer all. All you have to do if forgive just like Jesus did to us. 
it is amazing how powerful forginess can be.
