Forgiveness -is to stop feeling angry with somebody about something.
There are things that other people did to us which caused pain in our heart. Maybe your husband cheated, maybe you were raped, maybe your child or family member was murdered, this caused too much pain and you became angry and resentful. The pain grows every time you see that person.
I agree it is very difficult to even look at that person right now, but I want to tell you that forgiveness brings you inner peace and healing. When you forgive you are not doing it for the other person but you do it for yourself. Unforgiveness is a spiritual cancer and it eats you alive, you are the one who becomes more and more bitter, it steals your joy. Unforgivess opens doors for the devil to use us because anger can lead to sin.
It was difficult for God to forgive us after everything we did, He was angry before the blood of the lamb was presented before Him and the anger ceased because the blood was presented with love. It is hard but with the help of the Holy Spirit we can love our enemies and even pray for them. Love covers all sins, we see that when Jesus died for what He did not do because He loved us and wanted us to be reunited with God.
Take a step in forgiving those who wronged you so that you can be free from this bondage of hatred and be reunited with your stolen joy. Take your power back by forgiving, it also enables God to forgive you Matthew 6:14. You can do all things through Christ your strength. Take back what is yours. Shalom.
