Because angels love the Lord and share in that love with
others, they also possess all truth. As a result they possess
all wisdom and understanding, covering not only heavenly and spiritual subjects but also rational and earthly
ones. Love puts angels at the actual origins or source of
these things; that is, it makes angels aware of purposes
and causes. Love does this, because the Lord does it. To
see a thing in terms of its origins, or in terms of its purposes and causes, is to look from heaven at everything
below, even on earth.
