30. Verses 14-17 And God said, Let there be lights in the expanse of the heavens, to make a distinction between the day and the night; and they will be for signs, and for set times, and for days and years. And they will be for lights in the expanse of the heavens, to give light upon the earth; and it was so. And God made the two great lights, the greater light to have dominion over the day, and the lesser light to have dominion over the night; and the stars. And God set them in the expanse of the heavens to give light upon the earth.

No one can have an adequate understanding of what 'the great lights' are unless he knows what the underlying essence of faith is and how it develops in people who are being created anew. The very essence and life of faith is the Lord alone. In fact it is impossible for anyone who does not believe in the Lord to have life, as He Himself has said in John,

He who believes in the Son has eternal life; but he who does not believe in the Son will not see life, but the wrath of God will rest upon him. John 3:36.

[2] With people who are being created anew faith develops as follows: First of all they have no life, for life does not exist in anything evil and false but in what is good and true. Then they start to receive life from the Lord by means of faith - first by faith existing in the memory, which is factual faith, then by faith existing in the understanding, which is conceptual faith, and after this by faith existing in the heart, which is loving or saving faith. Factual faith and conceptual faith are represented in verses 3-13 by the inanimate, but faith made alive by means of love is represented in verses 20-25 by the animate. Consequently this is the first point at which love and faith deriving from it, which are called 'lights', are dealt with. Love is 'the greater light which has dominion over the day', and faith deriving from love is 'the lesser light which has dominion over the night'. And because they ought to make one the verb in the phrase 'let there be lights 'is singular and not plural.

[3] Love and faith have their place in the internal man as warmth and light do in the external, bodily man, and for this reason love and faith are represented by warmth and light. Therefore it is said that 'the lights' were set in the expanse of the heavens, that is, in the internal man - the greater light in his will and the lesser in his understanding. Yet they make their appearances in the will and understanding only as sunlight does in the objects it strikes. To the Lord alone belongs the mercy which moves the will with love and the understanding with truth or faith.

487. 'Days means periods of time and states in general. This has been shown in Chapter 1, where the 'days of creation' have no other meaning. In the Word it is very common for a whole period of time to be called 'a day', as it clearly is in the present verse and in verses 5, 8, 11, 14, 17, 20, 23, 27, 31, below; and therefore the states that belong to periods of time in general are meant by 'days' as well. And when 'years' is attached, then periods of years mean the natures of those states, and so the states in particular.

[2] The most ancient people had their own particular numbers which they would use to mean different aspects of the Church - for instance, the numbers three, seven, ten, twelve, and many which they obtained from these and other numbers - and in so doing incorporated states of the Church. These numbers therefore contain arcana that would require considerable effort to unravel. Really a number was an evaluation of the states of the Church. The same feature occurs throughout the Word, especially in the prophetical. And the religious ceremonies of the Jewish Church also entail numbers specifying periods of time as well as quantities; for example, in connection with sacrifices, minchahs, oblations, and other practices, which in every case have special reference to holy things. Consequently eight hundred in this verse, nine hundred and thirty in the next, and the numbers of years mentioned in the verses that follow after that, embody in particular more matters than can possibly be retold; matters, that is to say, which have to do with changes in the state of their Church in relationship to their own general state. Later on, in the Lord's Divine mercy, the meaning of the simple numbers up to twelve will be given, for without knowing these first of all no one can grasp what compound numbers mean.
