Andrew, I completely understand your position and hesitance to turn this into a preterist argument….because it is not.  For a while now preterism has “lost its soul” to dogmatism and the looking backwards that you are mentioning.  Personally I do not care how you come to the conclusion that the Kingdom is a present reality; whether it is a hermeneutic specific to Andrew Perriman or a remote spinoff of preteristic eschatology, living out the promises of God and participating actively into the manifestation of his presence and the fulfillment of the hope, as you mentioned, is key.

Disingenuous  or not, the article is great and preterists can learn a lot from your unique approach.
