The number "four" in the Bible represents things being linked together or joined. This is partly because four is two times two, and two represents the ultimate linking between our desire to be good and our understanding of truth. We can also see this in the fact that most buildings are rectangular, with the four sides linking together to make a whole. We also divide directions into four -- north, east, south and west -- and talk about the "four corners" of something meaning all of it. So our special thinking naturally looks at four sides as linking together into a whole.

17. In the Divine-Human One, infinite things are distinguishably one. It is recognized that God is infinite: he is in fact called the Infinite One. But he is called infinite because he is infinite. He is not infinite simply because he is intrinsically essential reality and manifestation, but because there are infinite things in him. An infinite being without infinite things within it would be infinite in name only.

The infinite things in him should not be called "infinitely many" or "infinitely all," because of our earthly concepts of "many" and "all." Our earthly concept of "infinitely many" is limited, and while there is something limitless about our concept of "infinitely all," it still rests on limited things in our universe. This means that since our concept is earthly, we cannot arrive at a sense of the infinite things in God by some process of shifting it to a higher level or by comparison. However, since angels enjoy spiritual concepts they can surpass us by changing to a higher level and by comparison, though they cannot reach infinity itself.
