A Portion of a Passage in Arcana Coelestia ~ Emanuel Swedenborg
... no truth can be produced unless there is a good or delight from which it is. In good and in delight there is life; but not in truth, except that which it has from good and delight. From this, truth is formed and begotten, and so is faith, which is of truth, formed and begotten by love, which is of good. It is with truth exactly as it is with light: except from the sun or a flame there is no light; it is from this that light is formed. Truth is only the form of good; and faith is only the form of love. Truth is formed from good according to the quality of the good, and faith is formed from love according to the quality of the love or charity.
(Arcana Coelestia 668)
