"There is therefore now no condemnation to those who are in Christ Jesus, who do not walk according to the flesh, but according to the Spirit. For the law of the Spirit of life in Christ Jesus has made me free from the law of sin and death." Romans 8:1,2
We do not need to walk around in a cloud of condemnation. We have forgiveness in Christ. If you have done something wrong, ask His forgiveness. You are immediately forgiven. You just have to accept that by faith. Jesus can do that. He can forgive us and He does. We have to forgive ourselves.
Get out from under that cloud and walk in the sunshine of forgiveness! It feels good. God can use your failures and turn them into something good!
