AC - 6663 - spiritual combat for eternal life & salvation

AC 6663
. . . he who defends his opinion against others who attack it,
confirms himself the more in his opinion,
and then also finds other confirmations of it
which he had not before observed . . .
and in this way he strengthens himself in his opinion . . ..
This is still more perfectly the case with spiritual combats,
because the combat takes place in the spirit,
and concerns goods and truths;
and especially because the Lord is present
and leads by the angels;
for the contest is concerning eternal life and salvation.
It is common in such combats
for the Lord to turn into good
all the evils which the hells intend;
wherefore it is not permitted them
to bring forth more or other evils
than can be turned into good that is suited to him
who is in combat.
The reason of this originates in the fact
that the Lord's kingdom is a kingdom of uses,
and therefore nothing can be done there
that is not a source of good.
