"If we claim to be without sin, we deceive ourselves and the truth is not in us. If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness." 1 John 1:8-9
God loves you. God loves you so much that He gave His one and only Son to live and to die for you. Paul says in Romans 5:8, "But God demonstrates his own love for us in this: While we were still sinners, Christ died for us." Paul also says in Romans that we are all sinners; there is no one who is good, no one who is righteous. The wages of sin is death, separation from God and His love. Satan wants you to believe that there is no hope, no love that can rescue you from your sin. Satan is a liar. God can and will forgive you, and God can and will restore you. John says that when you repent - take ownership of your sin and turn to God and confess it - that God will forgive you because He is faithful; God will purify you because He is faithful.
In the Bible, we are told time and time again of God's forgiveness and restoration. God forgave Moses of his sins, including murder. God restored Moses and used Him for the advancement of His kingdom. God forgave Paul, formerly Saul, for his sins, including the persecution and execution of Christ followers. God restored Paul unto Himself, and He used Paul for the advancement of His kingdom. God forgave Peter of his sins, including apostasy - publicly denying Jesus Christ. God restored Peter, and used him to advance His kingdom. God loves you. God will forgive you when you confess your sins to Him. God will purify you and restore you to a full life, an eternal life. God will use you to be a participant in His kingdom. He will use you to advance His kingdom right here, right now. Believe it! Claim it! Live it!
