The prophecies of the Lord's Advent can be stirring. Here's a much-loved one from Isaiah:

"The people who walked in darkness Have seen a great light; Those who dwelt in the land of the shadow of death, Upon them a light has shined." (Isaiah 9:2)

"The people who walk in darkness" symbolize people who have faith -- they are walking -- but it's a dim faith, without much knowledge of the genuine truths in the Word. And yet, they are receptive -- when the Lord is born, they welcome the Christian teachings when they hear them; they see a great light. See Arcana Coelestia 597.

The above words of Isaiah brought hope to people of Israel prior to the Lord’s birth on earth. The “great light” that would shine refers to a renewed sight of the Lord’s love and wisdom after a time of darkness.

These words can bring hope to us, too, in times of spiritual darkness and conflict. A new light can dawn in our minds—the start of spiritual renewal—and in the end, the Lord can be born in our hearts as a spirit of goodwill.

At Christmas, there's a special opportunity for this, as people all over the world are celebrating the Lord's birth. And... who doesn't need spiritual renewal?

The Bible generally uses two different terms for large groups: “people” and “nations.” When it uses “nation,” it is talking about a group with the desire for good as its ultimate underlying motivation; when it uses the term “people” it is talking about a group whose deep motivation is to seek true ideas and concepts. As with all symbolism in the Bible, this can be also used in a negative sense, to describe groups with the lust for evil or those driven by false concepts. It can also be used in the abstract, with “nation” representing desires for good themselves and “people” representing true ideas themselves. In a way, these meanings make sense if we look at the two words themselves. “People” brings to mind a collection of individuals, and that is somewhat how it is with ideas -- you can have many of them that inter-relate, but also stand somewhat on their own, individually. “Nation” is a more unified term, reflecting the way that a desire for good tends to unify other feelings.
