Both parties suffer

“God opposes the proud
       Jesus said, “Father, forgive them, for they do not know what they are doing.”^{.     The punishment inflicted on him by the majority is sufficient.  Suffering from a person who has  unforgiveness  is very heavy. You know that was what David went through with Absalom. Absalom blame his father for the injustice of his sister Tamar. ANd he did not like how David handle it. So that spirit of unforgiveness enter Abaslom cause him to rebelled against his father and to turn against his own father. He did not even want to be in his own company. He had people join his side, who knew David was kind etc.  David went through a lot because of Abaslom unforgiveness. Just to give you a bit of it. If you want to read the whole story look at 2 Samuel 13-18. Absalom ending was indeed tragic. You also suffer from the hand of the unforgiver. Whatever their actions and deeds are toward you.. As the word  of God says in  Matthew 18:28-“But when that servant went out, he found one of his fellow servants who owed him a hundred silver coins.[i] He grabbed him and began to choke him. ‘Pay back what you owe me!’ he demanded. Plus it gives the devil a foothold to your life. As the word of God says in 2 Corinthians 2:11-  in order that Satan might not outwit us. For we are not unaware of his schemes. So to handle a person who does not show you love is to treat them with kindness regardless of the deep pain they cause you. I know it hurts, and you can't  get the trauma out of your mind, and just have suffer so much by their hands.  But  remember to go to Jesus with your healing and let him heal you of your wounds and then tell him how you feel about that person or people. Trust in the Lord with all your heart. If he could forgive all of us, he sure can help  to you to forgive you too.}

If you want to have a relationship with Jesus say this prayer. Lord Jesus I am the one who has shown hatred toward you. I am the one who is alienated because of my sins. But thank you that you have shown me your kindness and overlook my faults. I love you Jesus very much. I love how you love very much. I thank you for dying, and being buried and rising again. So I can live with you forever. And now Good Savior fill me with your Holy Spirit.in Jesus Name.AMen
