154. Verse 19. I know thy works and charity, signifies the internal of those who are of the church. This is evident from the signification of "works," as being the things that are of the will, or of celestial love (of which see above, n. 98, and from the signification of "charity," as being the things that are of spiritual love. "Works and charity" signifies the internal of the church, because its internal is made up of the things that are of the will or love, and its external of the things that are of the understanding and faith. There are two loves that constitute heaven or the church, love to the Lord and love towards the neighbor, or charity; love to the Lord is called celestial love, and love toward the neighbor, which is charity, is called spiritual love. They are so called for the reason that heaven is divided into two kingdoms, one called the celestial kingdom, the other the spiritual kingdom, consequently the loves that govern there are so called (See the work on Heaven and Hell 13-19, 20-28 also The Doctrine of the New Jerusalem 54-62, 84-100, where also it is shown what celestial love is, and what spiritual love, namely, that celestial love is to do the commandments of the Lord from the affection of the will, and spiritual love is to do them from the affection of the understanding). There are two things that constitute heaven or the church with man, namely, love and faith. Love resides in man's will, for what man loves that he also wills; but faith resides in his understanding, for what a man believes that he also thinks, and thought is of the understanding.

[2] The internal of the celestial church, therefore, is to do the Lord's commandments from the affection of the will, consequently from the love of good; while the internal of the spiritual church is to do the Lord's commandments from the affection of the understanding, consequently from the love of truth. That doing the Lord's commandments is loving Him, He Himself teaches in John (John 14:21, 23). The internal of the celestial church is what is meant by "works," and the internal of the spiritual church is meant by "charity." (But as these things cannot be explained in a few words, so as to be clearly perceived, see what is said respecting them in The Doctrine of the New Jerusalem, on The Will and Understanding, n. 28-36; on The Internal and the External Man, n. 36-53; on Love in General, n. 54-64; on Love towards the Neighbor, or Charity, n. 84-107; on Faith, n. 108-122; and in the work on Heaven and Hell, where Celestial Love and Spiritual Love are treated of, n. 13-19)
