Making expiation for the Holy of Holies and for the Tent of Meeting because of the uncleanness and transgressions of the children of Israel signifies that although we have been redeemed and washed by the blood of Christ, because we are still in the old creation and still live in uncleanness, in our worship of God there is still the consciousness of sin and thus the need of the propitiation by the blood of Christ (1 John 1:710; 2:1-2). This consciousness of sin will continue until we are raptured and transfigured in our body (Phil. 3:21).
