A brief review of what he has asserted thus far:
Deuteronomy 32:35, "Their foot shall slide in due time."
In part one we read:
In this verse is threatened the vengeance of God on the wicked unbelieving Israelites, … The expression I have chosen for my text, Their foot shall slide in due time, seems to imply the following doings, relating to the punishment and destruction to which these wicked Israelites were exposed.
1. That they were always exposed to destruction;
2. It implies, that they were always exposed to sudden unexpected destruction. As he that walks in slippery places is every moment liable to fall,
3. Another thing implied is, that they are liable to fall of themselves, without being thrown down by the hand of another; as he that stands or walks on slippery ground needs nothing but his own weight to throw him down.
4. That the reason why they are not fallen already, and do not fall now, is only that God's appointed time is not come. For it is said, that when that due time, or appointed time comes, their foot shall slide.
The observation from the words that I would now insist upon is this. "There is nothing that keeps wicked men at any one moment out of hell, but the mere pleasure of God."
He continued in part 2:
The truth of this observation may appear by the following considerations.
1. There is no want of power in God to cast wicked men into hell at any moment.
2. They deserve to be cast into hell; so that divine justice never stands in the way, it makes no objection against God's using his power at any moment to destroy them.
3. They are already under a sentence of condemnation to hell.
4. They are now the objects of that very same anger and wrath of God, that is expressed in the torments of hell.
5. The devil stands ready to fall upon them, and seize them as his own, at what moment God shall permit him.
And now part 3:
6. There are in the souls of wicked men those hellish principles reigning, that would presently kindle and flame out into hell fire, if it were not for God's restraints. There is laid in the very nature of carnal men, a foundation for the torments of hell. There are those corrupt principles, in reigning power in them, and in full possession of them, that are seeds of hell fire. These principles are active and powerful, exceeding violent in their nature, and if it were not for the restraining hand of God upon them, they would soon break out, they would flame out after the same manner as the same corruptions, the same enmity does in the hearts of damned souls, and would beget the same torments as they do in them. The souls of the wicked are in scripture compared to the troubled sea, Isa. 57:20. For the present, God restrains their wickedness by his mighty power, as he does the raging waves of the troubled sea, saying, "Hitherto shalt thou come, but no further;" but if God should withdraw that restraining power, it would soon carry all before it. Sin is the ruin and misery of the soul; it is destructive in its nature; and if God should leave it without restraint, there would need nothing else to make the soul perfectly miserable. The corruption of the heart of man is immoderate and boundless in its fury; and while wicked men live here, it is like fire pent up by God's restraints, whereas if it were let loose, it would set on fire the course of nature; and as the heart is now a sink of sin, so if sin was not restrained, it would immediately turn the soul into a fiery oven, or a furnace of fire and brimstone.
8. Natural men's prudence and care to preserve their own lives, or the care of others to preserve them, do not secure them a moment. To this, divine providence and universal experience do also bear testimony. There is this clear evidence that men's own wisdom is no security to them from death; that if it were otherwise we should see some difference between the wise and politic men of the world, and others, with regard to their liableness to early and unexpected death: but how is it in fact? Eccles. ii. 16. "How dieth the wise man? even as the fool."
9. All wicked men's pains and contrivance which they use to escape hell, while they continue to reject Christ, and so remain wicked men, do not secure them from hell one moment. Almost every natural man that hears of hell, flatters himself that he shall escape it; he depends upon himself for his own security; he flatters himself in what he has done, in what he is now doing, or what he intends to do. Every one lays out matters in his own mind how he shall avoid damnation, and flatters himself that he contrives well for himself, and that his schemes will not fail. They hear indeed that there are but few saved, and that the greater part of men that have died heretofore are gone to hell; but each one imagines that he lays out matters better for his own escape than others have done. He does not intend to come to that place of torment; he says within himself, that he intends to take effectual care, and to order matters so for himself as not to fail.
10. God has laid himself under no obligation, by any promise to keep any natural man out of hell one moment. God certainly has made no promises either of eternal life, or of any deliverance or preservation from eternal death, but what are contained in the covenant of grace, the promises that are given in Christ, in whom all the promises are yea and amen. But surely they have no interest in the promises of the covenant of grace who are not the children of the covenant, who do not believe in any of the promises, and have no interest in the Mediator of the covenant.
