From Arcana Coelestia ~ Emanuel Swedenborg
When a man is in love and charity he is continually in worship, external worship being merely the effect.The angels are in such worship; with them, therefore, there is a perpetual Sabbath - from this the Sabbath, in the internal sense, signifies the Lord's kingdom. But man, while in the world, ought not to be otherwise than in external worship also; for by external worship internal things are excited, and by means of external worship external things are kept in holiness, so that internal things can flow in. And besides, man is thus imbued with knowledges, and is prepared for receiving celestial things, and is also gifted with states of holiness, although he is unaware of this; which states of holiness are preserved to him by the Lord for the use of eternal life, for in the other life all the states of his life return.
(Arcana Coelestia 1618)
