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.

101. The Lord is 'the east'. This too is clear from several places in the Word, as in Ezekiel,

He brought me to the gate, to the gate facing the way of the east. And behold, the glory of the God of Israel came from the way of the east, and His voice was like the voice of many waters, and the earth shone with His glory. Ezekiel 43:1-2, 4.

The Lord's being 'the east' was the reason for the sacred practice in the Jewish representative Church, before the Temple was built, of facing eastwards when praying.
