I do wish we’d spend, in the Church, much more time discussing what a ‘resurrection ethic’ is rather than the destiny of folks who honestly wonder about the nature and reality of a physical resurrection. Let’s talk about what it means, practically speaking, for any of us to ‘trust’ resurrection (in the positive James sense), rather than merely “believe in” it (in the negative James sense).
Ironically, the theological camps that tend to strip or minimize the Sermon on the Mount along with Jesus’ other ethical teachings, also have a very heavenly/after we die/resurrection focus. It seems to me that the resurrection gives the disciple the best (only?) possible footing to embolden him or her to actually follow the Sermon and the other teachings with any joy.
The ethical teachings of “love your enemy” and “offer the other (unslapped) cheek” or even “make good use of the things of this world without becoming attached to them” are very plausible within a body that will be resurrected. But I find the ethic impossible to do (with joy) without the hope of resurrection. Isn’t this certain hope the very thing that kept Jesus himself on the path of obedience? Trusting the resurrection is essential, foundational to the ethic (at least this one). One could even argue, I think, that the primary purpose of the resurrection is to allow/encourage God’s will (the ethic) to be done on earth as it is in heaven–for “sons of God” to be born into good works on the earth. Looking at your “image” post, maybe this is what we should be living and offering to people: “Trusting the resurrection of Christ (and the rest of humanity with him) makes an entirely different way of living possible–one based in joyful agape.”

I love ethics being grounded in a “now but not yet” framework. It does have bearing on our relationships across economic, political, and social boundaries.

Wow, I never thought of Jesus’ own hope of resurrection as being what kept him on the path of obedience. I have goosebumps. When he told Martha, “I am the Resurrection and the Life,” we often reduce his words to merely comfort for her grief. But Jesus was announcing the power of the resurrection!
