"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, and under the stars) is an echo of a far greater excellence, namely, the glory of God...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 disproportion between us and the universe is a parable about the disproportion between us and God. And it is an understatement."

- John Piper, from his book 'Don't Waste Your Life'
