From a passage in Arcana Coelestia ~ Emanuel Swedenborg
... the life of faith causes a man to be spiritual, but not faith except insofar as it has been implanted in the life. The life of man is his love, and that which he loves he wills and intends, and that which he wills and intends, he does. This is the being of man, but not that which he knows and thinks and does not will. This being of man cannot in any wise be changed into another being by thinking about mediation and salvation; but by regeneration anew, which is being effected during a great part of his life; for he must be conceived, born, and grown up anew; and this is not effected by thinking and speaking, but by willing and acting.
(Arcana Coelestia 7779:3)
