To mistake freedom from sin only on the conscious level of our lives for complete deliverance from sin by the atonement through the Cross of Christ is a great error. No one fully knows what sin is until he is born again. Sin is what Jesus Christ faced at Calvary. The evidence that I have been delivered from sin is that I know the real nature of sin in me. For a person to really know what sin is requires the full work and deep touch of the atonement of Jesus Christ, that is, the imparting of His absolute perfection.
