7195. 'And I also established My covenant with them' means the joining together that existed even then through the Lord's Divine Human. This is clear from the meaning of 'covenant' as a joining together, dealt with in 665, 666, 1023, 1038, 1864, 1996, 2003, 2021, 6804; and from the representation of Abraham, Isaac, and Jacob, to whom 'with them' - those with whom the covenant had been established - refers here, as the Lord's Divine Human, dealt with in 6804, 6847. From this it is evident what the internal sense of these words is, that the proximate or most immediate meaning of them is the union of the Divine itself with the Divine Human; and that the meaning following on from this is the joining together of the Divine itself with those who belonged to the spiritual Church through the Divine Human. For as has been shown a number of times already, those who belonged to the spiritual Church were saved through the Lord's Divine Human, see 6854, 6914, 7035, 7091 (end). The expression even then is used to link the meaning here to what comes immediately before - to indicate that the joining together existed when they were in a state involving temptations and gave no thought to Divine things within the Church. For the Lord is more present within a state involving temptations than He is outside it, though that is not at all how it seems, 840.

1023. That 'and I, behold I am establishing My covenant' means the Lord's presence in charity becomes clear from the meaning of 'a covenant', dealt with in 666, where it was shown that 'a covenant' means regeneration, and in particular the conjunction of the Lord with a regenerate person by means of love. It was also shown there that the heavenly marriage is the actual covenant itself, and that consequently the heavenly marriage exists with every regenerate person. The nature of this marriage or covenant has also been shown already.
[2] The heavenly marriage with the member of the Most Ancient Church existed in the area of his own will, but the heavenly marriage with the member of the Ancient Church came into existence in the area of his own understanding. Actually when the will part of man's mind had become utterly corrupted, the Lord in miraculous fashion separated the area of his own understanding from that corrupted will part, and within the area of man's own understanding He formed a new will, which is conscience. Into conscience He infused charity, and into charity innocence, and in this manner joined Himself to man, or what amounts to the same, established a covenant with him.
[3] To the extent that the area of a person's own will can be separated from this understanding part the Lord is able to be present with him, that is, to join Himself or establish a covenant with him. Temptations and similar means of regeneration render inactive the area of a person's own will, so that it is reduced to nothing and so to speak dies. To the extent that this happens the Lord can operate within charity by means of conscience implanted in the area of a person's own understanding. This is what is called 'a covenant' here.
