The plan of spiritual evolution is marked not only by God's will that we move ever in the direction of love, nut also by another of God's creative principles: that humanity has free will. What that means is that in any given moment, it is our choice whether we move toward love or retreat from it. What is not love is fear. But in the larger scheme of things, there is a limit past which lovelessness cannot remain. Fear is not life-giving enough to sustain itself. We can move in the direction of fear only so long before it brings us to our knees, or to our end.
