The Word of God convicts man of their sin, and that sin being known is like a death blow to us at first, then the freedom that comes from confessing such sinful ways causes our very heart's to rejoice! in the Lord as we are cleansed and healed!
The very confession of Jesus as Lord out of your mouth and belief from your heart that God raised Him from the grave is this very cleansing. Glory! Confess and Believe, and you too will be set FREE!
