AC 5826 - How do we find good through truth?

AC 5826 [5]
... in order that a person may be regenerated and become the church,
he must be introduced through truth to good;
and he is introduced when truth becomes truth in the will and in act.
This truth is good,
and is called the good of truth,
and produces new truths continually;
for then for the first time it makes itself fruitful.

The truth which is thence brought forth or made fruitful
is what is called internal truth,
and the good from which it is, is called internal good;
for nothing becomes internal until it has been implanted in the will,
because what is of the will is the inmost of a person.
So long as good and truth are outside of the will,
and in the understanding only, they are outside of a person;
for the understanding is without, and the will is within.
