And because at this point he starts to act from faith and also simultaneously from love, he becomes a spiritual man, who is called an image. The spiritual life of that man finds its delight in, and is sustained by, the things which are associated with cognitions of faith and with charitable acts, which are called his food; and his natural life finds its delight in, and is sustained by, those which belong to the body and the senses. The latter give rise to conflict until love rules and he becomes a celestial man.

Thus: here 'advanced in years' means, in the internal sense, entering that state in which He was to cast off the human, and so means that the time was at hand.
