2665. 'Everything which Sarah says to you, hearken to her voice' means that He was to act in accordance with spiritual truth. This is clear from the representation of 'Sarah' as the Divine spiritual or Divine Truth, dealt with in 2622, and from the meaning of 'hearkening to the voice' as acting in accordance with that Truth, dealt with in 2542. But as to what is meant by acting in accordance with spiritual truth, an intelligible explanation of this to others is less easy than the perception of it by those who know the internal sense. Consequently any statement made according to the way in which the latter perceive what is meant could hardly be recognized. And there is the further reason that more arcana have first to be brought out into the open and indeed to be believed before the matter can be explained and then enter into the ideas that constitute his belief. What it means in a general way can be described to some extent, namely that the Lord arrived at a conclusion from the Divine Human, and acted according to it, and so from His own power. For it was by means of Divine Truth that He united the Human to the Divine, and by means of Divine Good that He united the Divine to the Human. Regarding this reciprocal union, see 2004.
