8644. Moses’ father-in-law. That this signifies from which is good conjoined with truth Divine, is evident from the signification of “father-in-law,” as being the good from which is the good that is conjoined with truth (see n. 6827); and from the representation of Moses, as being truth Divine (n. 6752, 6771, 7010, 7014, 7382). The reason why “a father-in-law” signifies good from which is good conjoined with truth, is that “a wife” signifies good when “the man” signifies truth (n. 2517, 4510, 4823). As in what follows, the conjunction of Divine good with Divine truth is treated of, whereby a setting in order may be effected in the man of the church, be it known that between Divine good and Divine truth there is this distinction: that Divine good is in the Lord, and Divine truth is from the Lord. It is as with the fire of the sun and the light which is therefrom; the fire is in the sun, and the light is from the sun; in the light there is not fire but heat.

[2] Moreover in the other life the Lord is the Sun, and also is the light. In the Sun there, which is Himself, is Divine fire, which is the Divine good of the Divine love. From that Sun is Divine light, which is Divine truth from Divine good. In this Divine truth there is also Divine good, but not such as is in the Sun, it being accommodated to reception in heaven; for unless it were accommodated to reception, heaven could not have come into existence, because no angel can bear the flame from the Divine love. He would be consumed in a moment, as would a man if the flame of the sun of this world should blow directly upon him.

[3] But how the Divine good of the Lord’s Divine love is accommodated to reception, cannot be known by anyone, not even by the angels in heaven, because it is an accommodation of the Infinite to the finite; and the Infinite is such as to transcend all the understanding of the finite, insomuch that when the understanding of the finite desires to look in that direction, it falls as into the depth of the sea and perishes. (That the Lord is the Sun in heaven, and that the Sun there is the Divine good of His Divine love, and that the light therefrom is Divine truth, from which is intelligence, see n. 1053, 1521-1533, 1619-1632, 2776, 3094, 3138, 3190, 3195, 3222, 3223, 3225, 3339, 3341, 3636, 3643, 3993, 4180, 4302, 4408, 4409, 4415, 4523, 4533, 4696, 7083, 7171, 7174, 7270, 8197)

7083. The heat and light in the natural world arise from the sun of the world; but spiritual heat and light, or love and faith, arise from the sun of heaven. The sun of heaven is the Lord; the heat which comes from Him as a sun is love, and the light which comes from Him as a sun is faith. That the Lord is light is evident from these words in John:

Jesus said, I am the light of the world, he that followeth Me shall not walk in darkness, but shall have the light of life (John 8:12);

and that the Lord is a sun is evident in Matthew:

When Jesus was transfigured, His face shone as the sun, and His garments became white as the light (Matthew 17:2).
