It takes three to make love, not two: you, your spouse, and God. Without God people only succeed in bringing out the worst in one another. Lovers who have nothing else to do but love each other soon find there is nothing else. Without a central loyalty life is unfinished.
There is no justice in the laws of nature, no term for fairness in the equations of motion. The Universe is neither evil, nor good, it simply does not care. The stars don't care, or the Sun, or the sky.
But they don't have to! WE care! There IS light in the world, and it is US!
