A guest post by Jonathan Edwards
When the body enjoys the perfections of health and strength, the motion of the animal spirits are not only brisk and free, but also harmonious; there is a regular proportion in the motion from all parts of the body, that begets delight in the soul and makes the body feel pleasantly all over—God has so excellently contrived the nerves and parts of the human body. But few men since the fall, especially since the flood, have health to so great a perfection as to have much of this harmonious motion. When it is enjoyed, one whose nature is not very much vitiated and depraved is very much assisted thereby in every exercise of body or mind; and it fits one for the contemplation of more exalted and spiritual excellencies and harmonies, as music does.
But we need not doubt, but this harmony will be in its perfection in the bodies of the saints after the resurrection; and that, as every part of the bodies of the wicked shall be excruciated with intolerable pain, so every part of the saints’ refined bodies shall be as full of pleasure as they can hold; and that this will not take the mind off from, but prompt and help it in spiritual delights, to which even the delight of their spiritual bodies shall be but a shadow.
