I’m not sure I understand what you mean by your comment about the “now, but not yet fully.” Paul seems to have perceived that the new creation had already begun, signaled by the resurrection of Jesus and then the transformation of hearts to be able to live the life of the Age (“zoe tou aionou”—think i have my declension incorrecte, but you get the idea—eternal life, or sanctification). But he perceived this to be in conflict with the ongoing Present Evil Age. I think this is what people mean by the “now, but …” It doesn’t seem as much awkward as the way things happen to be as we await the fullness of that which we have already received a deposit (Ephesians 1). In that sense, we sometimes are out of sync with the rest of creation which is still waiting to join in the liberty that we have begun to taste (but not yet fully, Romans 8).

I don’t think the “now, but …” is that awkward to talk about, but I would gladly discard it, semantically, for the use of more biblical language, like talk about “the ages.” It seems to me that most people who use it now are more often using it as an easy explanation for why not everyone is healed when we pray for them rather than as a discussion of how our lives are lived in tension.

On a separate note, I’d like to read more about how Andrew and others see what he has written as distinctive from, if it is, the preterist view.
