Therefore, He must have had a reason for taking His time. In my opinion, God created a universe bigger than any human mind can comprehend over an unimaginably long number of years in order to demonstrate His absolute mastery and control over space and time. Birds, beasts, trees, flowers. Gnaws iron, bites steel, grinds hard stones to meal. Slays kings, ruins towns and beats high mountains down.
Time is the ultimate power in our universe.
Eventually, it destroys all of the works of man and nature. For as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts. Those who argue that the universe is smaller and younger than modern scientists describe are, in my mind, denying the infinite power and glory of God. Some will say that my brief treatment of the age issue here trivializes a number of important points. No doubt this is true, but I plead a lack of expertise and time.
