Maybe we’ve got this ass backwards. Maybe, on the Judgement Day, we will be doing the judging.
That is, God will allow us a taste of his omniscience, just enough for us to see everything we have ever thought and done, in context, to feel empirically all the effect we had on the world, to honestly see ourselves for the first time. We will judge ourselves.
Practically all of us will elect for damnation, of course.
And the task of Jesus, the Savior, will be to talk us out of it.
