38. Verse 18 And to have dominion over the day and the night, and to make a distinction between the light and the darkness; and God saw that it was good.

'The day' is used to mean good, and 'the night' evil. Consequently goods are called 'the works of the day', whereas evils are called 'the works of the night'. 'The light' is used to mean truth, and 'the darkness' falsity, just as the Lord says,

Men preferred darkness rather than light; he who does the truth comes to the light. John 3:19-21.

Verse 19 And there was evening, and there was morning, a fourth day.

3339. In the next life those forms of light, and also those forms of warmth, manifest themselves visually. Angels live within the light of heaven and also within the warmth that has been spoken of. From that light they receive intelligence, and from that warmth the affection for good. Indeed the forms of light seen with their external sight have their origin in the Lord's Divine wisdom, and the forms of warmth which are also felt by them have their origin in the Lord's Divine love. To the extent therefore that spirits and angels possess intelligence in truth and affection for good they are closer to the Lord.
