In God’s presence, all sin is forgiven and forgotten. Proverbs 16:6 (Msg) says Guilt is banished through love and truth; Fear-of-GOD deflects evil.
One way to rid oneself of guilt is via the power of love. As humans, we have a responsibility to realize that God loves you in spite of all you have done wrong. We have a responsibility to comprehend the fact that the love of God may even be shown on a greater level; that while we were in our most helpless position, Christ died for us (Romans 5:6). When you and I were at our lowest, He gave His life as a sacrifice for us. Although it is possible for a man to choose to die for another man, it is very unlikely that a man would die for a bad man (Romans 5:7). Despite the fact that we were evil, Jesus chose to die for us. How much more so now that God has adopted you as His child?
Be aware that God loves you and that there is nothing you can do to make God “unlove” you. God’s love for you cannot be earned or lost. This reality is more important than others. It is not to make you feel better about yourself when you act inappropriately. It does safeguard you from falling into sin in the first place, though. Take note that it is not the love that you have for God, rather the love that God has for you.
Try not to make an excuse for everything because the truth has tremendous power. After you have come to terms with this reality, your next step is to pray to the Lord, confess your sin to Him, and ask for forgiveness. God saw you while you were there. He knows everything that has ever happened and will ever happen. It is in your best interest to approach Him, get on your knees, and discuss the matter with Him.
It is complete folly for anybody to try to convince you that admitting your faults is beneath you or that you have no need to do so. Owning up to your wrongdoing is the same as confessing it. You must go to God and apologize (See James 5:16 KJV). Once you have finished doing this, you should stop asking the Father to pardon you for committing that sin every time you have a conversation with Him. You, on the other hand, are not a sinner but rather a child of God.
