I have been where you were, but God in His sovereign mercy delivered me from being a cheerleader for the other team. As I came to embrace the confidence of 'victory in Jesus' for the big picture, I began experiencing victory in Jesus in my own life, family, and vocation. All were transformed by a more consistently Biblical, and more optimistic, eschatology.
Why preach the failure of the gospel as good news? Only reason I can figure -- to excuse one's one mediocrity and failures in life. How long has it been since Christianity produced a Bach, Milton, or Michaelangelo? Today, the leading voice in the field of science fiction that honors the name of Jesus is a Mormon. There are reasons for mediocrity -- mainly, a lack of vision, and the consequent failure to engage in long-term disciplined pursuit of excellence for the glory of God.
You, sir, are puffed up in your own conceit. And, again, you are trying but failing to mischaracterize our point of view. Jesus already has the victory and success or failure is measured in His eyes, not ours.
Science fiction? Is that where you obtain your eschatology from?
