123. 7. It is the unceasing effort of the Lord's divine providence to unite us to himself and himself to us in order to give us the joys of eternal life; and this can happen only to the extent that our evils and their compulsions are banished. I explained in 27-45 that it is the constant effort of the Lord's divine providence to unite us to himself and himself to us, and that this union is what we call reformation and regeneration. I explained also that this is the source of our salvation. Can anyone fail to see that union with the Lord is eternal life and salvation? Everyone can see this who believes that we were originally created in the image and likeness of God (see Genesis 1:26-27) and who knows what the image and likeness of God are.

[2] If we are truly rational and use our rationality when we think and use our freedom when we try to think, can any of us believe that there are three gods equal in essence and that the divine Being or divine Essence can be divided? As for a threefold nature in one God, that is something we can conceive and understand, just as we understand the soul and the body of an angel or a person and the life that they bring forth. Further, since this threefold nature in a single Being exists only in the Lord, it follows that any union must be a union with him.

Use your rationality and think freely, and you will see this truth in its own light. First, though, admit that the Lord, heaven, and eternal life are real.

[3] Now, since God is one and since by creation we have been made in his image and likeness, and since we have come into a love for all our evils through our hellish love, its compulsions, and their pleasures, thereby destroying the image and likeness of God within us, it follows that it is the constant effort of the Lord's divine providence to unite us with himself and himself with us and thereby to make us his images. It also follows that the Lord is doing this so that he may give us the bliss of eternal life, since this is the nature of divine love.

[4] The reason he cannot make this gift, cannot make us images of himself, unless we banish sins from our outer self in apparent autonomy is that the Lord is not just divine love but divine wisdom as well; and divine love does nothing unless it stems from divine wisdom and is in accord with it. It is in accord with divine wisdom that we cannot be united to the Lord and thus reformed, regenerated, and saved unless we are allowed to act freely and rationally. This is what makes us human. Anything that is in accord with the Lord's divine wisdom is also in accord with his divine providence.

2943. 'To all entering into the gate of his city, saying' means matters of doctrine through which one comes to faith. This is clear from the meaning of 'a gate' as a place of entry and so as that which, in the same way as a door, leads in, dealt with in 2145, 2152, 2356, 2385, and from the meaning of 'a city' as truth, which constitutes faith, dealt with in 402, 2268, 2449, 2451, 2712. In the Ancient Church a city was not like the city of later or of modern times. That is to say, a city did not consist of a collection or gathering together of individuals but of separate families living side by side. A family descended from the same forefather constituted a city. The city of Nahor, for example, to which Abraham's servant went to betroth Rebekah to Isaac, Genesis 24:10, consisted of the family of Nahor which was there. And Shalem, the city of Shechem, to which Jacob came after his departure from Paddan Aram, Genesis 33:18 and the whole of Chapter 34, consisted of the family of Hamor and Shechem which was there. And the same was so with all other cities in those times.

[2] And as it had come down to them from the most ancient people that nations and families represented heavenly communities, and so the things of love and charity, 685, 1159, therefore when a city is mentioned instead of a family, and a people instead of a nation, truth that constitutes faith is meant. It is also why in the genuine sense the city of God and the holy city mean faith in the Lord. And as 'a city' meant faith, 'the gate of the city' means matters of doctrine through which one comes to faith. The same was also meant in the Jewish representative Church by the judges and elders sitting in the gate of the city and giving judgement there, as is evident from historical sections of the Word, and also in Zechariah,

These are the things that you shall do: Speak the truth, everyone to his companion; judge in your gates the truth and the judgement of peace. Zechariah 8:16.

And in Amos,

Hate evil, and love good, and establish judgement in the gate. Amos 5:15.

'A gate' also means the place of entry into the rational mind, and the rational mind is compared to a city, see 2851.
