'A nation,' as in Genesis 21:18, signifies the spiritual church which should receive the good of faith.

In Isaiah 1:4, this signifies evils of the will, or lusts, while people signify falsities of the understanding, or persuasions. (Arcana Coelestia 622)

In Psalm 106:5, this signifies the Lord's kingdom. (Arcana Coelestia 1416[5])

In Ezekiel 29:15, this signifies the gentiles who will no longer be under the dominion of external truths. (Arcana Coelestia 409, 410)

In Micah 7:16, this signifies people who trust in themselves. (Arcana Coelestia 249)

2699. 'For I will make him into a great nation' means the spiritual Church. This is clear from the meaning of 'a great nation' as the spiritual Church which was to receive the good of faith, dealt with above in 2669. The expression 'a great nation' is used because the spiritual kingdom is the Lord's second kingdom, also dealt with in that same paragraph. As the member of the spiritual Church is represented by Ishmael, so also is the spiritual Church itself represented by him, as well as the Lord's spiritual kingdom in heaven; for the image and likeness of the one exists in the other. The first state following desolation was described in the previous verse, which was a state of comfort and of the hope of help. Their second state following desolation is described in the present verse, which is a state of enlightenment and of renewal resulting from this enlightenment.

[2] Since these states are unknown in the world, for the reason mentioned previously that few at the present day are being regenerated, let the nature of this state be described as it is experienced by those who are being regenerated in the next life, where that state is very well known. After being comforted with the hope of help, those in the next life who have experienced vastation or desolation are raised up by the Lord into heaven, thus from a state of shade, which is a state of ignorance, into a state of light, which is a state of enlightenment and of resulting renewal, and so into joy which stirs their inmost feelings. It is indeed light into which they enter, of such a nature that it enables them to see not only with their eyes but also at the same time with their understanding. How much this light renews them may become clear from the contrary state from which they have been released. At that time some who have had a childlike disposition and whose faith has been simple appear to themselves in dazzling white garments. Some appear wearing crowns. Some are taken round to many angelic communities and are everywhere received charitably as brothers; and therefore all good that is gratifying to their new life is offered to them. Some are allowed to observe the vastness of heaven, that is, of the Lord's kingdom, and at the same time to discern the blessedness of those who are there, in addition to countless other things there which defy description. Such is the state of initial enlightenment, and of the feeling of renewal resulting from this, of all who come out of desolation.
