Selection from Arcana Coelestia ~ Emanuel Swedenborg
THERE MUST BE INFLUX AND OPERATION INTO EACH AND ALL THINGS OF WORSHIP
That it is so may be comprehended even by those who are wise from the world, for they know from their learning that natural influx, which is called by them physical influx, is not possible, but only spiritual influx; that is, that nothing can flow in from the natural world into heaven, but only from heaven into the world. From all this it can be seen how it is to be understood that the influx and operation of the Divine of the Lord are into each and all things of worship. That it is so has frequently been given me to experience; for it has been given me to perceive the very influx, the calling forth of the truths which were with me, their application to the objects of prayer, the affection of good that was adjoined, and the elevation itself.
Nevertheless a man must not let down his hands and await influx, for this would be to act like an effigy devoid of life; in spite of all he must think, will, and act as of himself, and yet must ascribe to the Lord everything of thought of truth and of endeavor of good; by so doing there is implanted in him by the Lord the capability of receiving Him and the influx from Him.
For man was created no otherwise than to be a receptacle of the Divine; and the capability of receiving the Divine is formed in no other way. When this capability has been formed, he afterward has no other will than that it should be so; for he loves the influx from the Lord, and is averse to any working from himself; because the influx from the Lord is the influx of good, whereas any working from himself is the working of evil. In such a state are all the angels in heaven; therefore by "angels" in the Word are signified truths and goods which are from the Lord, because the angels are receptions of these.
