AC 8780, 8783 - degrees of revelation (Exodus 19:9)

AC 8780 [2]
And Jehovah said unto Moses.
By revelation here in the internal sense is not meant revelation
such as was made to the Israelitish people from Mount Sinai,
namely, that the Lord spoke in a loud voice,
and the people standing around heard;
but such a revelation is meant as is not made with a loud voice,
but inwardly in a person.
This revelation is made by the enlightening of the internal sight,
which is of the understanding,
when a man who is in the affection of truth from good is reading the Word.
This enlightening is then effected by the light of heaven,
which is from the Lord as the sun there....
When the understanding is enlightened by that Divine light,
it then perceives that to be true which is true,
it acknowledges it inwardly in itself, and as it were sees it.
Such is the revelation of those
who are in the affection of truth from good when they are reading the Word.

AC 8783
Truth Divine is not received by anyone
unless it has been accommodated to his apprehension,
consequently unless it appears in a natural form and shape;
for at first human minds apprehend none but earthly and worldly things,
and not at all spiritual and heavenly things.
Wherefore if spiritual and heavenly things were set forth nakedly,
they would be rejected as if they were nothing,
according to the Lord's words in John:

If I have told you earthly things, and you believe not,
how shall you believe, if I told you heavenly things?
(John 3:12).
