“That measure is different for different “observers” moving at high speeds relative to each other, in the world that God has in fact created. The measure of time is created along with the physical universe and is just as stable as the other principles and laws of nature that God upholds moment by moment. But temporal measure does not apply to God any more than the laws and principles of nature do. God’s own infinite, pure eternity is not measured by physical reality.”
