No, that’s not incoherent at all, in fact it makes sense! I often get questions from people about what will happen when the universe will cease to exist, the sun will stop shining, and the planet will no longer support life.  My answer is that I have no clue, at least not biblically speaking.  I have absolutely no problem with a Creator re-newing this creation as a "final act of God" at that time.  But ultimately the Bible speaks nothing of what may happen in a distant future; it rather tells a covenantal story which as you said, deals with the vindication of Christ as the true Son of God (which also has historical connotations) and the historical deliverance of the people of God. This two-fold expectation was fulfilled and is history.

As far as the nature of the resurrection goes, that is another story which I am afraid you and I will not resolve over a casual web-interface…those are the kind of discussions that require face-to-face time, potentially involving various adult beverages.

Thanks for answering :)
