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.

8767. 'And keep My covenant' means thus leading a good life, and as a consequence being joined [to the Lord]. This is clear from the meaning of 'keeping the covenant' as leading a life in accordance with the commandments, thus a life governed by good, and so being joined to the Lord. The reason why 'keeping the covenant' means leading a life in accordance with the commandments, thus leading a good life, is that the stipulations of the covenant were all the things that had been commanded, which were called testimonies, judgements, laws, and statutes, in particular the Ten Commandments. All these were also called the covenant because it was established through them. The fact that keeping them is leading a life in accordance with them is evident from the meaning of 'keeping' in the Word. Many times it speaks of hearing the commandments and keeping them, and in those places 'hearing' means accepting them in faith, and 'keeping' accepting them in life, that is, leading a life in accordance with them. The reason why 'keeping the covenant' also means being joined [to the Lord] is that in an overall sense 'a covenant' means being joined together, 665, 666, 1023, 1038, 1864, 1996, 2003, 2021, 6804. It has this further meaning because a person who leads a life in accordance with the commandments is joined to the Lord. For the commandments teach about life and also impart life, thereby opening the way to heaven and opening one's eyes to see the Lord.
