6434. 'The blessings of your father will prevail over the blessings of my ancestors means that this Church will have spiritual good from the natural, but nor from the rational. This is clear from the representation of 'Joseph' as the spiritual Church, dealt with in 6417; from the representation of Israel, to whom 'father' refers here, as spiritual good from the natural, dealt with in 5801, 5807, 5806, 5812, 5817, 5819, 5826, 5833; from the representation in the highest sense of Isaac and Abraham, to whom 'ancestors' refers here, as the Lord's Divine Internal, 'Isaac' representing the Lord's Internal Divine Human or Divine Rational, 1893, 2066, 2072, 2083, 2630, 3012, 3194, 3210, and 'Abraham' the Lord's Divine itself, toll, 3251, 3439, 4615 (though in the relative sense Abraham and Isaac represent the internal aspect of the Lord's kingdom and Church, 6098, 6185, 6276). From all this one may in some measure see the meaning of 'the blessings of your father will prevail over the blessings of my ancestors', which is that the spiritual Church will have good from the natural or external man but not from the rational or internal man; for the good of the member of the spiritual Church exists in the natural and does not go beyond it, whereas the good [of the member] of the celestial Church exists in the rational. No one can possibly know this meaning unless he knows what 'Israel' and what 'Isaac and Abraham' represent, also where the spiritual Church's good exists and from where it originates.

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.
