We can see from this that even though there is space in heaven as there is in our world, nothing is evaluated on the basis of space, but only on the basis of state. Also spaces there cannot be measured the way they can in our world, but only seen out of and in accordance with the state of their deeper natures.
The essential first cause of all this is that the Lord is present to each individual according to that individual’s love and faith, and that everything looks near or remote depending on his presence, since this is what defines everything that exists in the heavens. This is what gives angels wisdom, since it provides them with an outreach of thoughts, which in turn affords them communication with everyone in the heavens. In a word, this is what enables them to think spiritually and not naturally, the way we do.
