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.

2661. 'Because of his son' means for the reason that He delighted in it, that is, in the first rational. This is clear from the meaning of 'son', that is to say, the son of the servant-girl, as the merely human or first rational, dealt with already. The reason for the grief is not actually mentioned here but it is nevertheless evident from what follows. Love is plainly the reason for that grief, for it is said [that Abraham was distressed] 'because of his son', and this son is the subject in verses 13-21 which follow. But so that it may be known why this grief existed, that is, why it is said that 'the matter was deeply distressing to Abraham because of his son', let the following few comments serve by way of illustration.

[2] The Lord did not come into the world to save those who are celestial, but to save those who are spiritual. The Most Ancient Church, which was called Man, was celestial, and if this Church had remained uncorrupted there would have been no need for the Lord to be born a human being. But as soon as it began to decline the Lord foresaw that the celestial Church would cease to exist altogether in the world, and therefore a prophecy was given there and then about the Lord's Coming into the world, Genesis 3:15. After the era of that Church there was no longer a celestial Church but a spiritual Church. The Ancient Church, which came after the Flood, was this spiritual Church, referred to many times in Volume One. This Church, or the people who belonged to the spiritual Church, could not have been saved unless the Lord had come into the world. This is what the Lord's words in Matthew are used to mean,

Those who are well have no need of a physician, but those who are sick. I did not come to call the righteous, but sinners to repentance. Matthew 9:12-13.

And the following in John are used with the same meaning,

And other sheep I have which are not of this fold; I must bring them also, and they will hear My voice, and there will be one flock and one shepherd. John 10:16.

And the same is also meant in the parable about the hundred sheep, in Matthew 18:11-13.

[3] Now seeing that 'Isaac', representing the Lord's Divine Rational, also means those that are celestial, who are called 'heirs', while 'Ishmael', representing the Lord's merely human rational, also means those that are spiritual, who are referred to as 'sons' - as may also be evident from what has been stated above in 2658 - the words used in the present verse therefore mean that because of His Divine Love the Lord suffered grief. This is also the meaning of what follows in verses 13-21, where Hagar's son and she his mother represent the spiritual Church, and where the subject is the state of that Church, that is, of those who are members of that Church, 2612. Any further declaration regarding these arcana is not as yet possible. All that can be stated here is that with the Lord when in the world all states of the Church were represented, and also the way in which those who belonged to it were to be saved through Him. Consequently the same states of the Church are also meant by those same names.
