It is tormenting to live life with a burden of guilt. Jesus bore our sins and the guilt associated with them, and in reality, once we have received forgiveness for any sin we have committed, there is no longer any guilt. When sin goes, guilt goes with it. Jesus not only forgives sin, He removes it completely. He remembers it no more, and to Him, it is as if it never happened. When we feel guilt after we have confessed and repented of a sin, we should tell the feeling that it is a lie. Don't let your feelings be the ruling factor in your life. The Bible says that we are justified in Christ, and I heard one theologian say that means that we stand before God just as if we had never sinned. Even if our feelings can't believe it, we can choose to live beyond our feelings and we can honor God's Word above how we feel. If we make right choices according to the Word of God, our feelings will eventually come in line with our good choices.
