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.

1. THE BOOK OF GENESIS

The Word of the Old Testament contains heavenly arcana, with every single detail focusing on the Lord, His heaven, the Church, faith, and what belongs to faith; but no human being grasps this from the letter. Judging it by the letter or sense of the letter, nobody views it as anything more than a record, in the main, of external features of the Jewish Church. Yet at every point there are internal features that are nowhere evident in the external, apart from the very few which the Lord revealed and explained to the Apostles, such as that sacrifices mean the Lord; that the land of Canaan and Jerusalem mean heaven, which is therefore called Canaan and the heavenly Jerusalem; and that Paradise is similar in meaning.
