Arcana Coelestia # 140
140. That 'a help suitable for him' means the proprium becomes clear from the nature of the proprium, and from what follows. But because the member of the Church dealt with here was inherently well-disposed, he was granted a proprium. But it [only] appeared to be his own, which is why it is called 'a help suitable for him'.
Psalms 90:1-3
1
Lord, you have been our dwelling place for all generations.
2
Before the mountains were brought forth, before you had formed the earth and the world, even from everlasting to everlasting, you are God.
3
You turn man to destruction, saying, "Return, you children of men."
