This is clear from the meaning of 'white' as that which is used with reference to truth, dealt with in 3301, 3993, 4007, 5319; from the meaning of 'teeth' in the genuine sense as the natural, for the hard parts of a person's body, such as his teeth, bones, and cartilages, correspond to the truths and forms of good that belong to the lowest parts of the natural; and from the meaning of 'milk' as the celestial-spiritual, or what amounts to the same, the good of truth, dealt with in 2184. The Lord's Divine Natural is said to be the good of truth when it is considered in relation to people who believe in and love the Lord; for members of the external Church are unable to go any higher in their thinking than the Lord's Divine Natural, whereas the thinking of members of the internal Church goes above the natural to the Internal. For the idea of the Lord formed by anyone who believes in Him is conditioned by how far he can rise in his thinking. Those who are aware of what the internal is can have an idea of the internal; but those who are not aware of what the internal is have an idea of the external. This is why the Lord's Divine Natural is said to be the good of truth, when in fact His entire Human is the Divine Good of Divine Love.

From this it may be seen how it comes about that flames in the Word mean goods that are the goods of love, and lights truths that are the truths of faith.
