There are no sinless christians, period. There are some schools of thought that describe the Justification as "imputed" but not yet fully complete, until we pass from our present corrupted by sin body into our Final Body, that of Christ.
That doesn't apply to the flesh, which is contrary to the Spirit. Previously cited in Gal. 5:17
Jesus in "hell" is a whole nother subject. And one that I don't buy into.
Well, bravo for at least making that distinction. There is no justification available for the body. It is flesh and it is contrary to the Spirit and against the Spirit. And the Spirit is likewise against the flesh.
Every believer bears, in their own flesh, the state of "contrariness." Just as Paul taught us. There is no way to justify that which is contrary to the Spirit and against the Spirit. It won't and can not happen.
God is no respecter of any person exactly on this ground, because "all" bear the contrary state of the flesh. And that, because of indwelling sin.
7 But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin. 8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. 10 If we say that we have not sinned, we make Him a liar, and His word is not in us. 1 John 1:7-10
The blood of Jesus cleanses us from all sin.
If we confess our sin, He is faithful to cleanse us from all unrighteousness.
If I walk in the light and the blood of Jesus cleanses me from all sin, what sin does His blood not cleanse me of?
