The concept of God giving us new, eternal bodies is beyond comprehension. A body, by very nature is temporary and limited.
Eternity doesn’t have edges. It doesn’t begin and end. Therefore it can’t have borders. You can’t look at it.
With a huge exception. Or irony. Also, within the concept of eternalness, is having no limitations…boundaries in the sense that you can’t say that the Eternal “CAN’T” do something.
So, on one hand, eternity can’t have visible borders, because it never ends and never begins. On the other hand, you can’t tell eternity what it can’t do.
God, the Eternal One, can do whatever He pleases.
