I think society has put an emphasis on revenge and not really forgiving and forgetting. Our mindset is now, "They did something bad to me, so now I'm gonna do the same or worse to them." This is not how its supposed to be. Yes, there will always be those people who just don't treat others too well, but we can't let that get to us. "Do not be overcome by evil, but overcome evil with good." (Romans 12:21) If someone does something wrong to you, don't go up to their face, slap them and call them out! Don't play their game. The first thing you should do is say, "Hey, if I offended you in any way or did something wrong to you that made you want to do this to me, I'm sorry." Or something of that sort. Forgiveness, in this case, is very important because it shows that you're different. You're overcoming evil with good. This makes satan furious! When I was in 8th grade I had these friends who were very close to me, I considered them my best friends. We did everything together! Then one day, after I had been gone on a 2 week trip, I came back to school excited to see my friends and finally hang out with them! But my friends didn't seem too excited to see me… they completely ignored me and stopped talking to me. When I went back home, I told my parents about the situation. Later on, my dad told me, "Jas, I think you should go to them and ask for forgiveness." I started freaking out when he said this because I didn't want to say sorry! I put myself in the attitude of, "I'm not going to say sorry for something I didn't do. If anyone is asking for forgiveness, its them." I, then, started playing the same game they were playing. Soon after, I started being angry at everything. Every little thing they did annoyed me. When this happens, we allow satan to come and put all kinds of lies into our heads and we start believing them. This went on for about 2 weeks. Finally, I couldn't take it anymore. I went up to them and said, "Look, I don't know what I did to you but whatever it is, I'm sorry. If offended you in any way, shape, or form, forgive me. I'm not doing this because I want to but because I want to be right with you and with God." I walked away awkwardly haha but I felt so much better afterwards. You have to know that you can't please everyone and even if you think you did nothing wrong, go and tell that person sorry for whatever it may be. And if it's vice versa, just say, "hey, I forgive you." But you have to mean it with your whole heart! Do your part and forgive, and God will do His part and deal with the rest.
