You can work back to God from the phenomenal universe, or you can move from the Creator to the phenomenal universe. Each implies the other. The Creator would not be the Creator if there were no universe, and the universe would cease to be if the Creator did not sustain it. The Creator does not exist prior to the universe in time; he does not exist in time at all. God creates the universe constantly; he is with it, not above or behind it. This is impossible to understand for you because you are a created thing and exist in time. But eventually you will return to your Creator and then you will again no longer exist in time.
