God gave us a conscience. It tells us when we have done wrong. God made us that way not to make us feel guilty all the time. Conscience calls us to confession. That's how God forgives us and gives us a clean conscience. Confession of sin is simply agreeing with God that we have done wrong. God wants us to have a clean conscience. "If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness" (1 John 1:9).
Christ died for all of our sins. When you confess sin to God, all of your sins are forgiven. The Bible teaches that God cleanses us upon confession of our sins. We are made clean before God through Jesus Christ. "The blood of Jesus Christ His Son cleanses us from all sin" (1 John 1:7). That's how God forgives us.
Why do some people refuse to confess their sin to God and receive cleansing through Christ? There are at least two reasons. First, they don't know the good news in Christ. Secondly, they don't really believe the good news. The believer's confession of sin brings immediate cleansing through Christ. We can have a clean conscience today.
Do you have a sin from the past that makes you feel guilty? Confess it to God. Believe the promise of His word. God will forgive you. That's how God forgives us. That's the reason Jesus died for all our sins. Thank God for cleansing you through Jesus Christ. God will forgive your sins and cleanse your conscience.
