Does the blood of Christ that fell to the earth have to stay there, or can God take it back up into heaven?
The blood did run down to the earth, but it does not have to remain there. God can bring it back into a container and present it in glory, and it was presented in heaven's throne room as an eternal testimony.
Les teaches that although the blood ran down to the earth and was taken up by that which was cursed, it is not hard for God to bring that blood back into a container He could present in glory. After Christ presented His blood in the very throne room of heaven, it remains for all eternity as the eternal testimony of why believers will be in glory. The believer's assurance rests not on good works but on Christ's finished work—He is our propitiation, sacrifice, brazen altar, labor of cleansing, candlestick, mercy seat, and the blood of the mercy seat.
