How could the blood that fell to the cursed earth be presented to God in glory?

God is not limited by the cursed earth; He can reclaim that blood into a container and present it in glory. After Christ presented His blood in heaven's throne room, it remains an eternal testimony of why believers are in glory.

Les explains that although the blood ran down to the earth and was, in picture, taken up by the cursed ground, God can bring that blood back into a container He could present in glory. Les does not think that is hard for God. His own idea is that after Christ presented His blood in the very throne room of heaven, it will be there for all eternity as an eternal testimony of why believers are in glory. When asked why we are here, the stock answer will be, “There sits the blood.” This is not based on our good works but on Christ’s finished work; He is our propitiation, the sacrifice, our brazen altar, our cleansing, our candlestick, the mercy seat, and the blood of the mercy seat.

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.
