Job xix, 25.
Reason too gives evident support to the resurrection of the flesh.
Therefore it is against the nature of the soul to be without the body. But nothing that is against nature can be lasting. Therefore the soul will not be for ever without the body. Thus the immortality of the soul seems to require the resurrection of the body. Now the soul separate from the body is in a sense imperfect, as is every part away from its whole, for the soul is part of human nature.
