It IS finished.

If any man or woman truly be in Christ, they have become a new creature. Old sins have passed away. And behold, all things have become new. Clean heart. Right spirit. If any man or woman is in Christ, they grow in grace. Not in sin. The natural man or woman cannot cease from sinning because they are not born again by the Spirit of God. "First the blade, then the ear, after that, the full corn in the ear". The grace of God that brings salvation has appeared to every man and woman, teaching them to deny ungodliness and worldly lusts. To live sober and holy in this perverse and adulterous world of iniquity.  The Son of God has shed forth his Spirit upon clean hearts and minds purged from an evil conscience by His Blood. Beware that any man or woman called a pastor, apostle, or teacher, deceive you by alluring through lusts of the defiled flesh. If we have access to the mighty weapons of God, then we can cast down evil imaginations and bring every thought into obedience to Jesus Christ whose grace is abundantly sufficient to keep us from falling and is able to preserve us in the power of His might as good soldiers of Jesus Christ. It is finished. "Be not faithless, but believing."
