AC 6119 - there is spiritual death when there is a lack of truth

AC 6119
Spiritual life consists in activities according to truths,
consequently in uses;
for they who are in spiritual life
have an appetite and a longing for truths with a view to life, that is,
that they may live according to them, thus with a view to uses.
So far therefore as they are able to receive truths
in accordance with which uses may be done,
so far they are in spiritual life,
because so far they are in the light of intelligence and of wisdom.
When therefore truths fail,
as is the case when a state of shade comes,
which is signified in the Word by "evening",
the spiritual life labors;
for such things present themselves as belong to the shade,
that is, to spiritual death;
for in this case they are not as before kept in the light,
but are in part let back into their own;
and hence there arises from the shade
an image of spiritual death, that is, of damnation.
