Having unforgiveness in your life can be a major hindrance to your deliverance, it can even be harmful to your body physically. It helps to know that Forgiveness is not a feeling or emotion, it’s a choice. Consider having a conversation with Jesus about the following, even if you “feel” like you can’t forgive. Trust me.
Remember that time doesn’t heal, Jesus heals when we forgive and release the hurt to Him and let Him heal.
