3281. 'And Isaac was a son of forty years' means from His own power by means of the conflicts brought about by temptations. This is clear from the representation of 'Isaac' as the Divine Rational, often dealt with already, from the meaning of 'forty' as temptations, dealt with in 730, 862, and from the meaning of 'years' as states, dealt with in 23, 487, 488, 493, 893, 2788. Consequently the internal sense of these words is that the Lord made His Rational Divine even as regards truth by means of the conflicts brought about by temptations, and so by His own power. For the Lord by His own power made everything human within Himself Divine by means of the temptations He underwent, as has been shown already in 1661, 1663, 1668, 1690, 1787, 2083, 2523, 2632, 2776, 3030, 3043, 3141.

2083. 'And you will call his name Isaac' means the Divine Rational. This is clear from Isaac's representation and also from the meaning of his name in the internal sense.

From Isaac's representation: As stated frequently already, 'Abraham' represents the Lord's Internal Man, 'Isaac' His Rational Man, and 'Jacob' His Natural Man. The Lord's Internal Man was Jehovah Himself. Because the Rational Man was conceived from the influx of the Internal Man into the External Man's affection for knowledge, 1896, 1902, 1910, it originated in the Divine thus joined to the Human. Consequently the first rational represented by 'Ishmael' was human, but it was made Divine by the Lord, and is then represented by 'Isaac'.

From the meaning of his name: He was given the name Isaac from the word for 'laughter', and because laughter in the internal sense means the affection for truth, which belongs to the rational, as shown above in 2072, Isaac accordingly here means the Divine Rational.

[2] From His own power the Lord made Divine everything that was human with Him. Thus He made not only the rational Divine but also the sensory part, interior and exterior, and so the body itself. In this way He united the Human to the Divine. It has been shown already that not only the rational, but also the sensory part, and so the whole body also was made Divine and Jehovah. This may also become clear to anyone from the fact that He alone has risen as to the body from the dead, and sits at the right hand of the Divine Power both with His entire Divine and with His entire Human. 'Sitting at the right hand of Divine power' means having all power in heaven and on earth.
