As all men are touched by God’s love, so all are also touched by the desire for His intimacy. No one escapes this longing; we are all kings in exile, miserable without the Infinite. Those who reject the grace of God have a desire to avoid God, as those who accept it have a desire for God. The modern atheist does not disbelieve because of his intellect, but because of his will; it is not knowledge that makes him an atheist…The denial of God springs from a man’s desire not to have a God—from his wish that there were no Justice behind the universe, so that his injustices would fear not retribution; from his desire that there be no Law, so that he may not be judged by it; from his wish that there were no Absolute Goodness, that he might go on sinning with impunity. That is why the modern atheist is always angered when he hears anything said about God and religion—he would be incapable of such a resentment if God were only a myth. His feeling toward God is the same as that which a wicked man has for one whom he has wronged: he wishes he were dead so that he could do nothing to avenge the wrong. The betrayer of friendship knows his friend exists, but he wished he did not; the post-Christian atheist knows God exists, but he desires He should not.
