AC 9303 - how to think about the Lord; AC 9304 - His care of us; AC 9310 - "to hear His voice"

AC 9303 [4-5]
But the ideas of the angels about the Divine,
the Trinity, and Proceeding . . . are founded upon one . . ..
The angels think
(and what they think they believe)
that there is one God,
and that He is the Lord;
that His Human is the Divine Itself in a form;
and that the holy proceeding from Him is the Holy Spirit;
thus that there is a Trinity,
but still it is One. 

An idea of this is obtained from the idea
that exists about the angels in heaven.
An angel appears there in the human form,
but still there are three things in him that make a one.
There is his internal, which does not appear before the eyes;
there is the external, which does appear;
and there is the sphere of life of his affections and thoughts,
which pours out from him to a distance.
These three make one angel.
But the angels are finite and created,
whereas the Lord is infinite and uncreated.
And as no person, or even angel,
can have any idea about the Infinite except from things finite,
therefore such an example may be given
in order to illustrate what the Trinity in One is;
and that there is one God;
and that He is the Lord,
and no other.

AC 9304
. . . the signification of "guarding,"
when said of the Lord, as being providence;
for providence consists in providing and foreseeing,
thus in leading to good and guarding from evil;
because good is provided by the Lord,
and evil is foreseen by Him);
and because evil is foreseen,
a person is guarded from it,
otherwise good cannot be provided.
And from the signification of "the way,"
as being truth . . ..

AC 9310 [3]
. . . "to hear His voice"
denotes to obey His commandments . . .
