To mistake conscious freedom from sin for deliverance from sin by the Atonement is a great error. No man knows what sin is until he is born again. Sin is what Jesus Christ faced on Calvary. The evidence that I am delivered from sin is that I know the real nature of sin in me. It takes the last reach of the Atonement of Jesus Christ, that is, the impartation of His absolute perfection, to make a man know what sin is.

The Holy Spirit applies the Atonement to us in the unconscious realm as well as in the realm of which we are conscious, and it is only when we get a grasp of the unrivalled power of the Spirit in us that we understand the meaning of 1 John 1:7, “the blood of Jesus Christ cleanseth us from all sin.” This does not refer to conscious sin only, but to the tremendously profound understanding of sin which only the Holy Ghost in me realizes.

If I walk in the light as God is in the light, not in the light of my conscience, but in the light of God — if I walk there, with nothing folded up, then there comes the amazing revelation — the blood of Jesus Christ cleanses me from all sin so that God Almighty can see nothing to censure in me. In my consciousness it works with a keen poignant knowledge of what sin is. The love of God at work in me makes me hate with the hatred of the Holy Ghost all that is not in keeping with God’s holiness. To walk in the light means that everything that is of the darkness drives me closer into the centre of the light.
