AC 3453 - acting from truth comes first then acting from good

AC 3453 [3]
Act precedes, a person's willing follows;
for that which a person does from the understanding,
he at last does from the will,
and finally puts it on as a habit;
and it is then insinuated in his rational or internal.
And when it has been insinuated in this,
the person no longer does good from truth, but from good;
for he then begins to perceive therein somewhat of blessedness,
and as it were somewhat of heaven.
