The really wonderful moments of joy in this world are not the moments of self-satisfaction, but self-forgetfulness. Standing on the edge of the Grand Canyon and contemplating your own greatness is pathological. At such moments we are made for a magnificent joy that comes from outside ourselves. And each of these rare and precious moments in life—beside the Canyon, before the Alps, under the stars—is an echo of a far greater excellence, namely, the glory of God. That is why the Bible says, “The heavens declare the glory of God, and the sky above proclaims his handiwork” (Psalm 19:1).
Sometimes people say that they cannot believe that, if there is a God, he would take interest in such a tiny speck of reality called humanity on Planet Earth. The universe, they say, is so vast, it makes man utterly insignificant. Why would God have bothered to create such a microscopic speck called the earth and humanity and then get involved with us?
Beneath this question is a fundamental failure to see what the universe is about. It is about the greatness of God, not the significance of man. God made man small and the universe big to say something about himself. And he says it for us to learn and enjoy—namely, that he is infinitely great and powerful and wise and beautiful. The more the Hubble Telescope sends back to us about the unfathomable depths of space, the more we should stand in awe of God. The disporportion between us and the universe is a parable about the disproportion between us and God. And it is an understatement. But the point is not to nullify us but to glorify him.
