In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight:
Note 19 at Col 1:22: We are holy, blameless, and unreproveable in His sight. God is a Spirit and sees us through our new, born-again spirits. Therefore, these three qualities are in our spirits, not our flesh. If we are only looking for these things in the physical realm, we will be disappointed and may even doubt that the Lord has really effected these changes in us.
Our born-again spirits are already righteous and truly holy (see notes 17-18 at Eph 4:24). This should be reflected in our physical lives, but as long as we are in this world, it will never manifest itself to the degree that it already has in our spirits. Praise the Lord that He sees us in Christ; i.e., in the spirit.
