He is not the God of the dead, but the God of the living — That is, (if the argument be proposed at length,) since the character of his being the God of any persons, plainly intimates a relation to them, not as dead, but as living; and since he cannot be said to be at present their God at all, if they are utterly dead; nor to be the God of human persons, such as Abraham, Isaac, and Jacob, consisting of souls and bodies, if their bodies were to abide in everlasting death; there must needs be a future state of blessedness, and a resurrection of the body to share with the soul in it.
