Every Christian struggles with the "old man". The fraud is the person who is not aware of their faults. This reflection of another person within us, this duality- is a part of the consciousness that leads us to depend upon God. He sees us as we have been and loves us nevertheless and that love is transforming us. Within that love and forgiveness is the seed of who we really are in Christ, growing in grace, and sometimes it seems we have so far to go-
I know in whom I have believed and I am persuaded He is able to keep that which I have committed to Him against that day
He that has begun a good work in you will finish it until the day of Jesus Christ
Therefore, since we have so great a cloud of witnesses surrounding us, let us also lay aside every encumbrance and the sin which so easily entangles us, and let us run with endurance the race that is set before us, fixing our eyes on Jesus, the author and perfecter of faith, who for the joy set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.
My little children, I am writing these things to you so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous; and He Himself is the propitiation for our sins; and not for ours only, but also for those of the whole world.
If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
