The Word tells us that none of us can do what is good on our own; our actions are good only if they come from the Lord.
The Word tells us in the following passage that to the extent that we are not purified from our evils, any good things we do are not good, any devout deeds are not devout, and we are not wise; but the reverse is the case if we are purified.
That is how our own intelligence is described. Egypt is mere facts; a horse is our understanding of those facts; chariots are religious teachings based on those facts; and riders are the intelligence we develop as a result. Of these qualities we read, "Woe to those who do not look to the Holy One of Israel and do not seek Jehovah." "He will rise up against the house of the malicious and against the aid of those who work iniquity" means the destruction of these qualities by evils. "Egypt is human, not God, and her horses are flesh, and not spirit" means that this understanding comes from our own sense of self-importance and that therefore there is no life in it. "Human" and "flesh" are our own sense of self, and "God" and "spirit" are life that comes from the Lord. The horses of Egypt are the intelligence that we claim as our own.
All these propositions lead to the conclusion that because the Divine is what makes heaven, the Divine is human in form.
It may be seen with somewhat greater clarity that this is the Lord's divine human from the references to Secrets of Heaven at the close of this chapter, since this collection provides a condensation. It can also be seen from these references that the Lord's human is divine, contrary to the belief in the church that it is not. This may be seen as well from the material about the Lord at the close of The New Jerusalem and Its Heavenly Teaching.
