AE 790b - a storehouse for the formation of the spiritual man

AE 790b [5]
That the spiritual mind may be opened and formed
it must have a storehouse from which it may draw its supplies;
since unless man has such a storehouse he is empty,
and in emptiness there can be no Divine operation.
This storehouse is in the natural man and it is its memory,
in which everything knowable can be stored up
and can be drawn forth from it.
In this storehouse for the formation of the spiritual man
there must be truths that are to be believed
and goods that are to be done, both of them from the Word
and from doctrine and preaching from the Word.
These man must learn even from infancy.

[14]
... but still it is the Lord who works all these arcana,
while man knows nothing about it;
all that man needs to do is to learn truths from the Word
and to live according to them.
