Here is a short list of principles that I personally find significant and which are taught in the passage I cited:
1.
An eternal progression of intelligences. A hierarchy that is not static, but which stretches on forever and ever, and He who is at the top invites all those beneath Him to ascend to his place:
And the Lord said unto me: These two facts do exist, that there are two spirits, one being more intelligent than the other; there shall be another more intelligent than they; I am the Lord thy God, I am more intelligent than they all.
And they who keep their first estate shall be added upon; and they who keep not their first estate shall not have glory in the same kingdom with those who keep their first estate; and they who keep their second estate shall have glory added upon their heads for ever and ever.
2.
The concept of an all-powerful God who is nonetheless concerned with the individual! Who, despite the fact that He rules among the Gods, is still mindful of the welfare of each individual and desires to initiate a peer-relationship with the least of His spirit offspring: The Lord thy God sent his angel to deliver thee from the hands of the priest of Elkenah.
I dwell in the midst of them all; I now, therefore, have come down unto thee to declare unto thee the works which my hands have made, wherein my wisdom excelleth them all, for I rule in the heavens above, and in the earth beneath, in all wisdom and prudence, over all the intelligences thine eyes have seen from the beginning; I came down in the beginning in the midst of all the intelligences thou hast seen.
3.
The concept of the eternal nature of the mind; the soul -- the unique intelligence that gives us identity. We, as an intelligent entity, existed before we came to this earth. And we will continue to exist after and forever: And God saw these souls that they were good, and he stood in the midst of them, and he said: These I will make my rulers; for he stood among those that were spirits, and he saw that they were good; and he said unto me: Abraham, thou art one of them; thou wast chosen before thou wast born.
4.
The purpose of our mortal existence and a much clearer understanding of the way it was made. No creatio ex nihilo. No magic snapping of divine fingers and the whole thing comes into being. No, a process! Almost scientific in its nature. And a specific purpose behind it all: to permit the offspring of deity to advance upwards to the stature of its parentage: And there stood one among them that was like unto God, and he said unto those who were with him: We will go down, for there is space there, and we will take of these materials, and we will make an earth whereon these may dwell;
And we will prove them herewith, to see if they will do all things whatsoever the Lord their God shall command them;
And they who keep their first estate shall be added upon; and they who keep not their first estate shall not have glory in the same kingdom with those who keep their first estate; and they who keep their second estate shall have glory added upon their heads for ever and ever.
5.
The concept that this entire plan is being opposed by a very real force in the universe. There is a tangible opposition that is acting upon us, and therefore forcing us to either act or to permit ourselves to be acted upon. In a day when the very idea of a “devil” is all but universally looked upon with derision; as a quaint artifact of a day when demons and dragons dwelt in every dark forest, there is this confirmation that there is a basis for the idea of an adversary. There is an adversary, and he is very motivated to thwart the designs of God and those who followed God instead of him: And the Lord said: Whom shall I send? And one answered like unto the Son of Man: Here am I, send me. And another answered and said: Here am I, send me. And the Lord said: I will send the first.
And the second was angry, and kept not his first estate; and, at that day, many followed after him.
I think I could probably add upon this list if I were to ponder a while. But this will suffice for now. Those five concepts I listed above are definitely part of my philosophical foundation; at the very root of what I believe and how I see myself in this life.
