Hugh Ross has observed that once God has finally conquered evil, not only will He dispense with this earth but also he will no longer employ our current laws of physics:
* electromagnetism evidently will be unnecessary, because our light will emanate from the Godhead
* gravity, too, will no longer function, as evidenced by the New Jerusalem: under the current law of gravity, no object that large can be cubic, because gravity would have rounded its corners
I agree with Hugh that the physical laws will change. We have no idea how they will change, so I can’t go along with his categorical statements about electromagnetism and gravity. But he might be right.
There is so much we don’t know about physics, let alone the spiritual realm, what we don’t know alone could explain everything.
Then there is Jesus’s statement, ‘Behold! I am making all things new!” An eighth day of creation, after the sabbath of rest that began with Adam and Eve. The phrase ‘all things’ is comprehensive, including all laws and physical constants.
Who knows? Aside from God.
