In the Christmas story, the wise men bring gifts to the Lord: gold, frankincense and myrrh.

The gold is listed first, because it is the inmost - signifying good, e.g. the good that we do when we love the Lord and the neighbor.

The frankincense is next. It signifies rational truth, which is the set of true ideas that we know, not about external things like cars or cooking, but about what is really good, and what is really true.

These rational truths are built on earlier knowledges that we learn, before we have really made them our own. Those early knowledges about spiritual things - often learned in childhood - are represented by the myrrh.

In a way, these gifts are really a reciprocation. We can't actually give them to the Lord until the Lord has given them to us. We necessarily start out by learning and doing the Lord's law (myrrh). The Lord can then call up those memories to become rational truths (frankincense). Then, over time, and with effort, those truths can be transformed into good (gold). The wise men from the East had gone through this process of learning and becoming vessels that could receive truths and goods. They were able to perceive the Lord's birth, and find him, and bring gifts to him.

5621. 'Wax and stacte' means the truths of interior natural good. This is clear from the meaning of 'wax', in this case aromatic wax, as the truth of good, dealt with below; and from the meaning of 'stacte' too as truth derived from good, dealt with in 4748. The truths of interior natural good are meant because these spices are purer substances than resin or honey, and for that reason the mention of them comes second. For in the Word order determines the way in which such substances are listed. 'Wax' is not used here to mean ordinary wax but an aromatic kind, such as storax. This kind of wax is what the word in the original language is used to describe; and the same word is used for spice. From this one may see why this aromatic wax means the truth of good; for all spices, because they are sweet smelling, mean in the internal sense truths that are derived from good.

[2] This may be recognized from the consideration that in heaven truths derived from good are perceived with the same pleasure as sweet scents in the world. Also, when angels' perceptions are converted into odours, which in the Lord's good pleasure happens frequently, they are therefore detected as fragrances coming from spices and from flowers. This is why frankincense and incense were prepared from odiferous substances and put to a sacred use, and also why aromatic substances were mixed with oil for anointing. Anyone who does not know that the cause behind those practices lay among the perceptions enjoyed by those in heaven may suppose that they were practices enjoined solely to make external worship pleasant and that they held nothing of heaven and nothing holy at all within them, consequently that such religious practices held nothing Divine within them. See what has been shown already on these matters:

Frankincense and incense, as well as the fragrant substances in oil for anointing, were representative of spiritual and celestial things, 4748.

Spheres of faith and love are converted into pleasant odours; and therefore pleasant and sweet-smelling odours, also aromatic ones, mean the truths of faith which are derived from the good of love, 1514, 1517-1519, 4618.
