As I see it, the present tense of a high priest now, is the work of the cross and the shed blood in the past tense. The blood has a voice. Remember the blood of Able? The present tense of interceeding is the past tense of the given blood of Jesus.

...as I see it.

I don't see a man in heaven standing between sinners and a holy God advocating on behalf of sinners as an intermediary.

If that were the case, I could then easily see how that the advocate (the one in between) would plead with the one on the throne for grace and to send the other one as a comforter to the poor supplicant.

God in three persons blessed trinnnnnnity!
