AE 820a - truth from good, the first of the church

AE 820a [2]
. . . truth is the first thing through which a person has the church.
But it must be truth from good,
for truth without good is mere knowledge that a thing is so;
and mere knowledge does nothing
except to make a person capable of becoming a church;
but this is not effected until he lives according to knowledges.
Then truth is conjoined to good,
and a person is introduced into the church.
Moreover, truths teach how a person ought to live;
and when a person is affected by truths for the sake of truths,
which is done when he loves to live according to them,
he is led by the Lord,
and conjunction with heaven is granted him,
and he becomes spiritual,
and after death an angel of heaven.
