Heaven is still there, but not the part of it that was a level over earth.
Wait. Heaven is still over earth, just not the part that's over earth?
Heaven ... is New Jerusalem
And where is this? Inside our physical universe? Outside it?
Since Jesus built that, I would think that there was another abode before that was complete, that He ascended to.
So if I'm to understand correctly, your chronology is that God removed heaven from above earth at some point post-flood, then Jesus ascended into some kind of temporary heaven that wasn't above earth but still there, then when he was there, built a New Jerusalem where heaven currently is.
Doubt it all you like
In other words, you're right and I'm wrong. Not a great stance to be taking for debate.
if you look into it, you will see that God's son really fits the bill for many of the descriptions.
You don't think that maybe this means that things "out of heaven" could just be similar to one another? Assuming biblical inerrancy and all. Nowhere in the NT does it say that Jesus
was those heavenly hosts encountered in the OT.
