Rom. 8:1-2 So now there is no condemnation for those who belong to Christ Jesus. For the power of the life-giving Spirit has freed you through Christ Jesus from the power of sin that leads to death.
There is no condemnation for those who are in Christ because He has taken care of our sin problem. He graciously forgives us for whatever we have done and has forever taken it out of our hearts. He has put all of our sins underneath His blood and given us in their place His righteousness and holiness. He changes the essence of who we are so that we can now be children of God and live lives that honor Him.
There is no condemnation because the Holy Spirit has freed us from the power of sin that leads to death. The end result of sin is separation from God. It keeps us away from God and makes us incapable of doing anything that pleases Him. Sin is a barrier that we cannot cross to get to God. But, because Jesus has broken the power of sin's hold on us, the Spirit is able to break down those barriers that separate us from God. He frees us up so that we can live in, and enjoy, fellowship with God.
Don't let Satan deceive you into thinking that you are not good enough for fellowship with God. Don't let him convince you that all of your sins have not been forgiven. Don't let him get away with holding you down with false guilt or shame over forgiven sins. Forgiven sins and forgotten sins. They are no more in God's eyes. Christ's righteousness has taken care of them for you. Satan is a liar. Shut him out and ignore him.
There is no condemnation for a true child of God. Now, live like you have been set free.
