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?

597. 'Noah' means a new Church, which must be called the Ancient Church to distinguish between the Most Ancient Church before the Flood and the Church that followed it. The states of those two Churches were entirely different. The state of the Most Ancient Church was one in which people had from the Lord a perception of good and of truth deriving from it, while that of the Ancient Church, or Noah, came to be one in which it had a conscience concerning good and truth. The nature of the difference between having perception and having conscience is what determined the difference in state between the Most Ancient Church and the Ancient.

[2] Perception is not the same as conscience. Celestial people have perception, spiritual people conscience. The Most Ancient Church was celestial whereas the Ancient was spiritual. The Most Ancient Church possessed immediate revelation through direct contact with spirits and angels, and also through visions and dreams from the Lord. These experiences enabled them to know in a general way what good and truth were, and once they knew them in this general way their general or so to speak primary matters of knowledge were confirmed by means of countless details acquired through perceptions. These countless details constituted the particular and the individual aspects of the general knowledge to which they had reference. In this manner general or so to speak primary knowledge was being corroborated day by day. If anything was not in keeping with general matters of knowledge they perceived that it was not; and if anything was in keeping they perceived that it was. Such is also the state of celestial angels.

[3] The general, so to speak primary, matters of knowledge of the Most Ancient Church were celestial and eternal truths: for example, that the Lord governs the whole universe; that the Lord is the source of all good and truth; that the Lord is the source of all life; that man's proprium was nothing but evil, and in itself something dead; in addition to other general truths such as these. And they received from the Lord a perception of countless considerations confirming and harmonizing with these truths. For those people love was the chief thing of faith, and through love they were allowed by the Lord to perceive anything that was a matter of faith. Consequently faith to them was love, as stated already. The Ancient Church however became entirely different. That difference will in the Lord's Divine mercy be discussed later on.

2069. 'Kings of peoples will be from her' means truths that are the product of truths and goods joined together, meant by 'kings of peoples'. This is clear from the meaning of 'kings' as all truths in general, dealt with above in 2015, and from the meaning of 'peoples' also as truths, in general all things that are spiritual. For 'kings' are spoken of in reference to peoples, and not so much in reference to nations except when the nations mean evils, dealt with in 1259, 1260. In the prophetical part of the Word kings and peoples are mentioned many times, but nowhere are they used to mean kings and peoples, for at no point are kings and peoples the subject in the Word proper, which is the internal sense, but the celestial and spiritual things comprising the Lord's kingdom, and so goods and truths. The sense of the letter expresses itself by means of perceivable objects, as anyone does with words, merely to enable understanding.

[2] Since the subject here is Sarah and the promise that 'kings of peoples will be from her', and since 'Sarah' means Divine Truth which was the Lord's, 'kings of peoples' clearly means truths that are the product of truths and goods joined together, which are all the truths of the internal Church, that is, the interior truths of faith. Because these truths come from the Lord, they are frequently called 'kings' in the Word, and also 'a king's sons', as shown above in 2015.

[3] Anyone may see that some internal Divine matter lies concealed in the words that 'kings of peoples will be from her'. For the subject in this verse is Isaac, of whom it is said, 'I will bless him, and he will become nations', but of Sarah that 'kings of peoples will be from her'. Almost the same was also said of Abraham in verse 6 above, that 'kings will go out of him'; but it did not say as it does of Sarah, 'kings of peoples'. The arcanum within this lies too deep to allow it to be uncovered and described in a few words. From the representation and meaning of 'Abraham' as Divine Good and from the representation and meaning of 'Sarah' as Divine Truth the arcanum is to some extent evident, namely that from the Lord's Divine Good meant by 'Abraham' all celestial truth will come forth and have its being, and from the Lord's Divine Truth meant by 'Sarah' all spiritual truth will do so. Celestial truth is the truth which exists with celestial angels, and spiritual truth that which exists with spiritual angels. Or what amounts to the same, celestial truth was the truth which existed with members of the Most Ancient Church which came before the Flood and which was a celestial Church, spiritual truth that which existed with members of the Ancient Church which came after the Flood and was a spiritual Church. For angels, as also members of the Church, are distinguished into celestial and spiritual. That which distinguishes the celestial from the spiritual is love to the Lord, and that which distinguishes spiritual from celestial is love towards the neighbour.

[4] No more can be said about celestial truth and spiritual truth however until the difference between the celestial and the spiritual is known, or what amounts to the same, the difference between the celestial Church and the spiritual. For this see Volume One, in 202, 337, 1577; then concerning the nature of the Most Ancient Church and the nature of the Ancient Church, in 597, 607, 640, 765, 1114-1125, and in many other places. On the point that possessing love to the Lord constitutes the celestial, and possessing love towards the neighbour the spiritual, see 2023.

[5] These considerations now show what the arcanum is, namely that 'the kings who will go out of Abraham', referred to in verse 6, mean celestial truths that flow in from the Lord's Divine Good, while 'the kings of peoples who will be from Sarah', referred to in the present verse, mean spiritual truths that flow in from the Lord's Divine Truth. For the Lord's Divine Good is unable to flow in except with the celestial man since it is an influx into the will part of his mind, as was the case with the Most Ancient Church, whereas with the spiritual man the Lord's Divine Truth is flowing in since the influx is solely into the understanding part, which in him has been separated from the will part, 2053 (end). Or what amounts to the same, celestial good is flowing in with the celestial man, and spiritual good with the spiritual man. As a consequence the Lord is seen by celestial angels as the Sun, but by spiritual angels as the Moon, 1529, 1530.
