4108. 'To come to Isaac his father, to the land of Canaan' means so as to be joined to the Divine Good of the Rational, in order that the Human might be made Divine. This is clear from the representation of 'Isaac' as the Divine Rational, dealt with in 1893, 2066, 2083, 2630, and specifically as the Divine Good of the Rational, 3012, 3194, 3210; and from the meaning of 'the land of Canaan' as the Lord's heavenly kingdom, dealt with in 1607, 3481, and in the highest sense - that is, when the subject is the Lord - as His Divine Human, 3038, 3705. From these meanings it is evident that 'to come to Isaac his father, to the land of Canaan' means so as to be joined to the Divine Good of the Rational, in order that the Human might be made Divine.

[2] As regards the joining together of the rational and the natural in man's case, it should be realized that the rational constitutes the internal man and the natural the external man, and that the joining together of these produces the human. The nature of that human is determined by that of the joining together of the two; and they exist joined together when they act as one. And they act as one when the natural acts as the servant and is subservient to the rational. With man this is not possible unless it is done by the Lord, but with the Lord He did it by Himself.

1893. That 'Sarai, Abram's wife, bore him no child' means that the Rational Man did not as yet exist will be clear from what is said later on, when Isaac is the subject, for everyone, as has been stated, has an internal man, a rational man which is in between, and an external man, which strictly speaking is the natural man. These, as they existed with the Lord, were represented by Abraham, Isaac, and Jacob - the Internal Man by Abraham, the Rational Man by Isaac, and the Natural Man by Jacob. The Lord's Internal Man was Jehovah Himself, for He was conceived from Jehovah. This was why so many times He referred to Jehovah as His Father, and why in the Word the Lord is called 'the only begotten of God' and 'God's only Son'. The rational man does not exist with anyone when he is first born, only a potentiality to become rational, as may become clear to anyone from the fact that new-born babes do not possess reason but become rational as time goes by through the response of the senses to stimuli from without and from within, as knowledge and cognitions are bestowed on them. Rationality does, it is true, appear to exist with children; but rationality does not in fact do so, only something of the first beginnings of it, as may be recognized from the fact that reason resides with people who are adult and advanced in years.

[2] The Lord's Rational Man is the subject in the present chapter. The Divine Rational itself is represented by Isaac, but the first rational before it had become Divine is represented by Ishmael. Here therefore the statement that 'Sarai, Abram's wife, bore him no child' means that the Divine Rational did not as yet exist. As stated already, the Lord was born in the same way as any other, and as regards what He derived from Mary His mother He was like any other. And because the rational is formed through facts and cognitions which enter in by way of the external senses, or the senses that belong to the external man, His first rational was therefore born as it is with any other. But since everything human in Him was made Divine by His own power, so was the rational made Divine. His first rational is described in the present chapter, and once more in Chapter 21, where again in verses 9-21 Hagar and Ishmael are the subject, where it is said that Ishmael was cast out when Isaac, who represents the Divine Rational, had grown up.
