My perspective strongly identifies the phrase "the kingdom of god" with Isaiah's vision of the mountain, which is firmly of this world and our time. It is a making-right of this world that we should never forget to strive for.

The mistake that rather a lot of my evangelical cousins make (i am not one) is that, to paraphrase James, they tend to be so focused on the life to come and have such a crabbed interpretation of "staying unblemished by the world" that they entirely forget -- or worse, regard as something that blemishes you -- the "visiting the widows and orphans in their distress" clause. And that just won't do.
