597. And his feet as pillars of fire, signifies Divine truth, or the Word in ultimates, which is natural, sustaining interior things there, and full of the good of love. This is evident from the signification of "feet," as being in reference to the Lord the Divine good of natural Divine love, which is the ultimate in Divine order (see above, n. 65, 69); from the signification of "pillars," as being lower truths which sustain the higher (see above, n. 219); and from the signification of "fire," as being in reference to the Lord the Divine love (see also above, n. 68, 496, 504).

Divine truth in ultimates means the Word in the sense of the letter; and because this sense is natural, and the natural is the ultimate of Divine order, therefore this is what sustains spiritual and celestial Divine truth, exactly as pillars sustain a house or feet sustain the body; for without the natural sense of the Word its interiors, which are spiritual and celestial, would fall apart, like a house when its pillars are removed. Each and all things, therefore, that are in the natural or ultimate sense of the Word are perpetual correspondences, that is, they correspond to the spiritual and celestial things that are in the heavens, and thus also they signify them. From this it can in some measure be seen how natural Divine truth, which is the Word in the world, sustains spiritual and celestial Divine truth, which is Divine truth in heaven, as pillars sustain a house. This makes clear also why the feet of the angel were seen as "pillars of fire."
