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.

20. 4. The spiritual sense of the Word has been previously unknown. Every single thing found in nature corresponds to something spiritual. So, too, every single thing found in the human body. This is something we showed in the book Heaven and Hell 87-115. But what correspondence is has been previously unknown, even though in very ancient times it was quite well known. For people who lived then, the study of correspondences was the supreme study, and so universal that all their manuscripts and books were written in terms of correspondences.

[2] The book of Job, which is an ancient book, is full of correspondences.

Egyptian hieroglyphics, and also the fables of antiquity, were full of them too.

The ancient churches were all representative of things pertaining to heaven. Their rites and likewise their statutes, in accord with which their worship was instituted, consisted of nothing but correspondences.

So, too, everything connected with the church among the descendants of Jacob. Their whole burnt offerings and other sacrifices in their every particular were correspondent forms. Likewise the Tabernacle, with everything in it. And their feasts as well, such as the Feast of Unleavened Bread, the Feast of Tabernacles, and the Feast of Firstfruits.

So also the priesthood of Aaron and the Levites, including the holy vestments of Aaron and his sons. And all the statutes and judgments as well which had to do with their worship and life.

[3] And because Divine emanations in the world manifest themselves in correspondent forms, therefore the Word was written solely in terms of correspondences. Because the Lord spoke in accordance with His Divinity, He consequently spoke in terms of correspondences. For whatever emanates from the Divine, descends into such expressions in nature as correspond to their Divine origins, and these expressions then conceal within them the Divine contents called celestial and spiritual.
