AC 1502 - the arcana (secrets) hidden in the Word

AC 1502 [2-3]
These things would not have been related in the Word . . .
unless these arcana had been concealed within them.
Moreover this is the Word of the Lord,
which can in no wise have any life,
unless there is an internal sense that has regard to Him.

The arcana which lie stored up in these things,
as also in those said concerning Abram and Isaac in Philistia,
are-how the Lord's Human Essence was conjoined with His Divine Essence,
or what is the same,
how the Lord became Jehovah as to His Human Essence also;
and that His inauguration went on from childhood,
which inauguration is here treated of.
Moreover these things also involve more arcana than anyone can ever believe;
but those which can be told are so few as to be almost nothing.
Besides the most profound arcana concerning the Lord,
they also involve arcana
concerning the instruction and regeneration of a person,
that he may become celestial;
as also concerning his instruction and regeneration,
that he may become spiritual;
and not only concerning the instruction of the individual person,
but also concerning that of the church in general.
And, further, they involve arcana
concerning the instruction of little children in heaven;
in a word,
concerning the instruction of all
who become images and likenesses of the Lord.
These things do not at all appear in the sense of the letter,
for the reason that the historical narrative veils them over and obscures them;
but they appear in the internal sense.
