Do you realize how hard it is to imagine the new heaven and the new earth the Scriptures talk about? And even if we could get our finite minds around the idea of something new (better, improved)... I mean, how can it be better than the one we see described by John in the Revelation?
It just boggles the mind.
And more than that, once we get a glimpse of all that heaven includes, life on earth seems like, as Keith Green once said, "livin' in a garbage can."
