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.
