Selection from Arcana Coelestia ~ Emanuel Swedenborg
The progress of man's regeneration
from external to internal — from the truth of faith to the good of charity
The truth of faith is external, and the good of charity is internal. In order that the truth of faith may live, it must be introduced into the will, that it may there receive life; for truth does not live from knowing, but from willing.
Life flows in from the Lord through the new willing that He creates in man. The first life manifests itself by obedience, which is the first of the will; the second by the affection of doing the truth, which is the progression of the will, and which exists when delight and bliss are perceived in doing the truth. Unless there takes place such a progress of faith, truth does not become truth, but becomes a separate affair from life, sometimes confirmative of falsity, and sometimes persuasive of it, thus a foul affair; for it couples itself with the man's evil affection, or cupidity; that is, with his own proper will, which is contrary to charity. Such is the faith that by many at this day is believed to be faith, and to save without the works of charity.
