We love the morning, because we know that there will be night soon! We love the night, because we know that there will be morning soon! Who loves the morning if there shall be no night? Who loves the night if there shall be no morning?
We often speak of love when we really should be speaking of the drive to dominate or to master, so as to confirm ourselves as active agents, in control of our own destinies and worthy of respect from others.
We shall say without hesitation that the atheist who is moved by love is moved by the Spirit of God; an atheist who lives by love is saved by his faith in the God whose existence (under that name) he denies.
