Thanks!

@Robby,
I think I understood Doug's question, but I just disagree with the premise. I suppose viewing it in the way Doug couched it would dovetail nicely with the idea of an eternity of humans being born and being in need of an intercessor. It would also harmonize with the thought that we might need interceding in Heaven, should one choose to go down that path of thought. However, in either case, I think this is reading more into the passage than is warranted. A person can choose to highlight certain points in an analogy, without that analogy being followed all the way out. Many commentators for instance, fall into the trap of trying to figure out every feature of Jesus' parables, so that the main point is lost. In this case, I see the comparison between Jesus' role as High Priest versus the Levitcal priesthood as focusing on the superiority of Jesus' priesthood--that's all. I do not see the need to extrapolate from this passage that Jesus will continue to function as a priest into perpetuity.
As a side note, I could suggest that in one sense the priesthood continues forever, and that is that since he is High Priest of the New Covenant, and since the purpose of the New Covenant is to take out a people for God's name to be part of Abraham's seed, then the effects of the New Covenant extend forever, and so the priesthood would continue forever.
Regards, Brenden.
