So if they both end will God end?
We who believe the bible do not waste our time on what we can not know...But one thing we do know is that time exists and God is operating within that time spectrum, at least for the time being...
Operating in, but not subject to. God has no limits. space has 3 dimensions (Length, width, and depth). Time is the 4th dimension, duration. Space and time did not exist until God created them. God existed before He created them and will continue to exist after they are both gone.
Where do you get the idea that space will end???
