20. Anyone who has learned about God's order can also understand that man was created so as to become an angel, because in him order reaches its ultimate stage (see 9 above). In this stage something of the wisdom of heaven and the angels can be formed, and it can be reconstituted and multiplied. God's order never stops half-way, and forms anything there without the ultimate stage; for it is not in its fullness and perfection unless it goes to the ultimate. But when it is there, then it takes shape and uses the means at its disposal there to reconstitute and extend itself, which it does by reproduction. The ultimate is therefore the seed-bed of heaven.

This too is what is meant by the description of man and his creation in the first chapter of Genesis:

God said, Let us make ¹ man in our image, according to our likeness. And God created man in His image, in the image of God did He create him. Male and female He created them; and God blessed them, and God said to them, Be fruitful and multiply. Genesis 1:26-28.

Creating in the image of God and in the likeness of God means conferring on him the whole of God's order from first to last, and so making him an angel as regards the interiors of his mind.

3167. 'And to [her] mother' means to natural truth also, that is to say, spiritual things passed from the rational to it, even as they passed to natural good, dealt with just above. This is clear from the meaning of 'a mother' as the Church, which by virtue of truth is called 'a mother', dealt with in 289, 2717. So that people may know how spiritual things pass to natural good and to natural truth as a result of truth being introduced into good in the rational, a brief description must be given here. Everyone has an internal and an external, his internal being called the internal man, and his external the external man. But few know what the internal man is and what the external. The internal man is one and the same as the spiritual man, and the external man one and the same as the natural man. The spiritual man depends for understanding and wisdom on things that belong to the light of heaven, whereas the natural depends for its understanding and wisdom on things that belong to the light of the world. Regarding those two kinds of light, see 3138. For in heaven none but spiritual things exist, whereas in the world none but natural exist. The human being was created in such a way that in him spiritual things and natural things, that is, his spiritual man and his natural man, should accord with each other or make one. But in that case the spiritual man ought to have control over the things in the natural, and the natural man ought to obey, like a servant his master.

[2] Through the Fall however the natural man started to raise itself above the spiritual man and so turn Divine order itself upside down. As a consequence the natural man separated itself from the spiritual, and spiritual things could not reach it any longer except so to speak through chinks to provide the ability to think and speak. But so that spiritual things might flow in once more into the natural man this had to be regenerated by the Lord, that is, truth from the natural man had to be introduced and joined to good in the rational. When this happens spiritual things have access to the natural man, for now the light of heaven flows in and illuminates things in the natural man, and causes what is there to receive light. The goods there receive the warmth that the light conveys, which is love and charity, whereas the truth receives rays of light, which is faith. It is in this way that spiritual things pass from the rational into natural good and truth. Natural good in that case consists in all the delight and satisfaction gained from having service to the spiritual man as the end in view, and so service to the neighbour, more so to one's country, more so still to the Lord's kingdom, and above all to the Lord. And natural truth consists in all doctrinal teaching and factual knowledge which have wisdom, that is, the performance of those things, as the end in view.
