37. As for the statement that 'the lights will be for signs, and for set times, and for days, and for years', this contains more arcana than can be presented at this point, though no arcanum at all is visible in the sense of the letter. For now only this can be said: Change in spiritual and celestial things takes place both on general and on particular scales, and is comparable to changes that take place through the day and through the year. Changes through the day are from morning to midday, from then on to evening, and through the night to the morning. Changes in the year similar, from spring to summer, from then on to autumn, and through winter to spring. These bring changes in temperature and amount of daylight, and so in the fertility of the earth. Compared to such changes are the changes that take place in spiritual and celestial things. Life without changes and variations would lead to sameness, and so no life at all. Good and truth would not be recognized and identified, let alone perceived. In the Prophets such changes are called 'ordinances', as in Jeremiah,

[Thus] said Jehovah who gives the sun for light by day and the ordinances of the moon and of the stars for light by night, These ordinances will not depart from before Me. Jeremiah 31:35-36.

And in the same prophet,

Thus said Jehovah, If I have not established My covenant of day and night, the ordinances of heaven and earth . . . Jeremiah 33:25.

But these things will in the Lord's Divine mercy be dealt with at Genesis 8:12.

1733. 'Possessor of heaven and earth' means the conjunction of the Internal Man, or Jehovah, with the Interior and the Exterior Man. This is clear from the meaning of 'heaven and earth'. That which is interior in man is called 'heaven', and that which is exterior 'earth'. The reason heaven means that which is interior in man is that man as regards interior things is an image of heaven, and so a miniature heaven. The Lord's Interior Man primarily is heaven, for the Lord is the All in all of heaven, and thus heaven itself. The exterior man's being called 'the earth' follows as a consequence of this. Here also is the reason why 'the new heaven and the new earth' described in the Prophets and in the Book of Revelation is used to mean nothing other than the Lord's kingdom and every person who is the Lord's kingdom, that is, who has the Lord's kingdom within him. As regards heaven and earth having these meanings, see 82, 911, for heaven, and 82, 620, 636, 913, for earth.

[2] That 'God Most High, Possessor of heaven and earth' here means the conjunction of the Internal Man with the Interior and Exterior Man in the Lord becomes clear from the consideration that the Lord as regards the Internal Man was Jehovah Himself; and because the Internal Man or Jehovah guided and instructed the External Man - as the Father did the Son - the External Man considered in relation to Jehovah is therefore called the Son of God, but in relation to the mother the Son of Man. The Lord's Internal Man, which is Jehovah Himself, is that which is here called 'God Most High', and until complete conjunction or union had taken place it is called 'Possessor of heaven and earth', that is, Possessor of all that resided in the Interior and Exterior Man, which, as has been stated, is here meant by 'heaven and earth'.
