9373. Come up unto Jehovah. That this signifies conjunction with the Lord, is evident from the signification of “coming up,” as being to be raised toward interior things (see n. 3084, 4539, 4969, 5406, 5817, 6007), consequently also to be conjoined (n. 8760). That it denotes conjunction with the Lord, is because by “Jehovah” in the Word is meant the the Lord, (n. 1343, 1736, 1793, 2004, 2005, 2018, 2025, 2921, 3023, 3035, 5663, 6280, 6303, 6905, 8274, 8864, 9315). A secret which also lies hidden in the internal sense of these words, is that the sons of Jacob, over whom Moses was the head, were not called and chosen; but they themselves insisted that Divine worship should be instituted among them (according to wh at has been said in n. 4290, 4293); and therefore it is here said, “and He said unto Moses, Come up unto Jehovah,” as if not Jehovah, but another, had said that he should come up. For the same reason in what follows it is said that “the people should not go up” (verse 2); and that “Jehovah sent not His hand unto the sons of Israel who were set apart” (verse 11); and that “the appearance of the glory of Jehovah was like devouring fire on the top of the mountain in the eyes of the sons of Israel” (verse 17); and lastly that Moses, being called the seventh day, “entered into the midst of the cloud.” For by “the cloud” is meant the Word in the letter (n. 5922, 6343, 6752, 6832, 8106, 8443, 8781); and with the sons of Jacob the Word was separated from its internal sense, because they were in external worship without internal, as can be clearly seen from the fact that now, as before, they said, “all the words which Jehovah hath spoken we will do” (verse 3); and yet scarcely forty days afterward they worshiped a golden calf instead of Jehovah; which shows that this was hidden in their hearts while they were saying with their lips that they would serve Jehovah alone. But nevertheless those who are meant by “the called and the chosen” are those who are in internal worship, and who from internal worship are in external; that is, those who are in love to and faith in the Lord, and from this in love toward the neighbor.

This term refers to good things we do for other people. Such actions are done sincerely without any expectations for something in return. This last part is a key component of the concept of good works as intentions really determine everything (See Arcana Coelestia 6393). The Lord flows into good works, and the person doing them moves to a higher spiritual state.

Good works are connected to faith. A life of faith requires one to perform good works. Otherwise, a person is not actually living a life of religion. This is shown at the very beginning of Doctrine of Life:

“Religion is all about how we live, and the religious way to live is to do good.”

Of course, there is a bit more nuance to the matter (e.g. what's really good? who is it good for? over what time range?) but that’s what is all comes down to – doing good.

3337. CORRESPONDENCES AND REPRESENTATIONS - continued

What correspondences are, and what representations are, may be seen from what has been stated and shown already; namely that correspondences exist between things belonging to the light of heaven and those belonging to the light of the world, while representations consist of things belonging to the light of heaven which manifest themselves within those belonging to the light of the world, 3225. But what the light of heaven is, and the nature of it, cannot be known so easily by man because he dwells within the things that belong to the light of the world. And to the extent he dwells within these the things that exist within the light of heaven are seen by him as darkness and as nothing at all. These two, the light of heaven and the light of the world, are what form the whole of man's intelligence, when life is flowing in.

[2] In man mental images are nothing else than the forms and shapes of such things as he has been taking in with his physical sight - forms and shapes wonderfully diverse or, as I will call it, modified. His interior mental images or thought however are nothing else than the forms and shapes of such things as he has absorbed with his mental sight - forms and shapes even more wonderfully diverse or, as again I will call it, modified. Things which come into being in this way are not in themselves animate but are made so from the influx of life from the Lord.
