Have you settled in your heart that you're done with sin and are sold out to Jesus Christ? Jesus' power and heart are to immediately free you from all sin–forever. The conversions in the book of Acts, and the teaching in Romans 6, prominently proclaim this awesome message of immediate, total deliverance!
Is total freedom in Jesus your present experience? If not, you have nowhere else to look but the stubbornness of your own heart. You don't have to stay in your miserable condition one more minute. The blood of Jesus is here to set you free!
