AE 654c - to be instructed

AE 654c [15-16]
Jacob with his sons, who were then called the sons of Israel,
went down by command into Egypt,
and dwelt in Goshen,
which was the best of the lands of Egypt,
and there remained a long time.
(Gen. 46, et seq.)
This was done because a person must be instructed in truths
scientifically and naturally before he is instructed spiritually.

[16] For every person, by truths scientifically and naturally understood,
acquires for himself a rational
into which the spiritual can flow in and operate;
for through the rational which belongs to his understanding
a person receives the light of heaven, which is spiritual light,
and through the rational enlightened by the spiritual
he surveys cognitions and knowledges,
selecting from them such as are in accord
with the genuine truths and goods of heaven and the church,
which are spiritual,
and rejecting those that are not;
thus it is that a person lays the foundation of the church in himself.

. . ."to sojourn" in the Word signifies to be instructed.
