The denial of God—or the blithe bracketing of the
question of God—is not a harmless parlor game. Rather, it carries with it the
gravest implications. If there is no God, then our lives do indeed belong to
us, and we can do with them what we want. If there is no God, our lives have no
ultimate meaning or transcendent purpose, and they become simply artifacts of
our own designing. Accordingly, when they become too painful or too shallow or
just too boring, we ought to have the prerogative to end them. We can argue the
legality and even the morality of assisted suicide until the cows come home,
but the real issue that has to be engaged is that of God’s existence.
