29. THERE ARE THREE HEAVENS.

There are three heavens, entirely distinct from each other, an inmost or third, a middle or second, and an outmost or first. These have a like order and relation to each other as the highest part of man, or his head, the middle part, or body, and the lowest, or feet; or as the upper, the middle, and the lower stories of a house. In the same order is the Divine that goes forth and descends from the Lord; consequently heaven, from the necessity of order, is threefold.
