Suppose we were to take a compass and insert the point and draw the outline of a circle. The center point is the same distance from any point on the circumference. …Let us suppose that this circle is the world and that God himself is the center: the straight lines drawn from the circumference to the center are the lives of human beings. …Let us assume for the sake of the analogy that to move toward God, then, human beings move from the circumference along the various radii of the circle to the center. But at the same time, the closer they are to God, the closer they become to one another; and the closer they are to one another, the closer they become to God.
