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.

233. Investigating mysteries of faith by means of facts is as impossible as it is for a camel to go through the eye of a needle, or for a rib to control the tiniest fibres of the chest and the heart. Just as gross, indeed far more gross, is what is sensory and factual in comparison with what is spiritual and celestial. Anyone who wishes to probe merely the secrets of nature, which are countless, discovers scarcely a single one, and when he starts to probe he sinks, as is well known, into falsities. What then would happen if he wished to probe the secrets of spiritual and celestial life, where thousands and thousands of secrets exist for each one contained in the unseen parts of nature?

[2] To illustrate the point, let just one example be taken. Of himself man is incapable of anything other than doing evil and turning himself away from the Lord. Yet it is not the man who does so but the evil spirits residing with him. Yet again it is not the evil spirits who do it but the evil itself which they have made their own. All the same, man does that evil and turns himself away, and is blameworthy, even though his life comes from the Lord alone. On the other hand man of himself cannot possibly do good and return to the Lord. This is accomplished by angels. Yet the angels cannot do it, but only the Lord. All the same, man is capable as if of himself of doing good and of returning to the Lord. The truth of all this cannot possibly be grasped by the senses, formulated knowledge, or philosophy. If these are consulted they deny those things outright, even though they are inherently true. And the same applies with everything else.

[3] These considerations show that people who consult sensory evidence and factual knowledge in matters of belief plunge themselves not only into doubt but also into denial, that is, into thick darkness. And in plunging into thick darkness they also become immersed in every kind of evil desire, for in believing what is false they also do what is false. And when they believe that the spiritual and the celestial do not exist they believe that only the bodily and the worldly do so. So they love anything that belongs to self and the world, and this is how evil desires and evils themselves arise out of what is false.
