21. Verses 4-5 And God saw that the light was good; and God made a distinction between the light and the darkness. And God called the light Day, and the darkness He called Night.

The light is called good, because it comes from the Lord, who is good itself. 'The darkness' is those things which were there prior to the person's new conception and birth. They were seen as light, because evil was seen as good, and falsity as truth. But in reality they are darkness and things proper to that person which are lingering on. All things that are the Lord's, being things of light, are compared to the day, and all that are man's own, being those of thick darkness, are compared to the night, as is done many times in the Word.

6505. 'And forty days were completed for him' means states of preparation through temptations. This is clear from the meaning of the number 'forty' as temptations, dealt with in 730, 862, 2272, 2273; and from the meaning of 'days' as states, dealt with in 23, 487, 488, 493, 893, 2788, 3462, 3785, 4850. The fact that they are states of preparation is meant by the words 'days were completed for him'; for the completion of that number of days allowed preparation to be made so that bodies might be preserved from putrefaction, by which in the spiritual sense is meant the preparation that is made so that souls may be preserved from the corruption of evil. For more about the removal of evils and falsities by means of temptations, and a person's preparation through temptations to receive truths and forms of good, see 868, 1692, 1717, 1740, 2272, 3318, 4341, 4572, 5036, 5356, 6144.
