Throughout much of history, most of humankind has struggled hard to eke out a living from this earth, and so it was easy to interpret Genesis as implying that work is the curse for disobeying God. One of the good points of modern society is that an ever greater percent of humans can find purpose and pleasure from ‘making a living’. Like you, Christy, I cannot contemplate a Heaven where there is no useful occupation. Postulating that the Scriptural reference to the Kingdom of God could take place on a “redeemed earth” seems orthodox to me. But if , as I hope is the case, the majority of humankind eventually is found worthy of heaven, this planet will be awfully crowded even with resurrected bodies than no longer need nourishment.
Is it too unorthodox to postulate that the spirits that now inhabit our bodies will, upon our demise, enliven other bodies that are created on other planets–perhaps to conscious creatures whose predecessors never fell from God’s grace? Such creatures would have a jump start on the return journey from Alpha to Omega.
