Well, there's this idea in the Bible of heaven and earth becoming one. In the garden of Eden, man, God, and the whole host of heaven lived together, but then got separated (exiled). And eventually we will all live together again. New Jerusalem is seen coming down from heaven onto the new earth. There's going to be a feast at some point, so that sounds cool, too. Exodus mentions a feast that Moses and a few others had with God on the mountain, so this speaks to that. It's really interesting! The Bible Project does these cute cartoon videos on various themes running throughout the Bible. I had not noticed them before!
But who knows?! We read the word, the promises made and we have hope. We see glimpses of realities to come (for those who have eyes to see and ears to hear). It makes life whimsical and full of wonder!
But, just a question for atheists:
Believers sometimes have doubts about their belief, and that's ok. Do atheists ever have doubts about their unbelief? Even for a second? Just wondering!
