Charles Spurgeon Commentary Deuteronomy 8:18-19

"But thou shalt remember Jehovah thy God, for it is he that giveth thee power to get wealth; that he may establish his covenant which he sware unto thy fathers, as at this day. And it shall be, if thou shalt forget Jehovah thy God, and walk after other gods, and serve them, and worship them, I testify against you this day that ye shall surely perish." — Deuteronomy 8:18-19 (ASV)

But thou shalt remember the LORD thy God: for it is he that giveth thee power to get wealth, that he may establish his covenant which he sware unto thy fathers, as it is this day. And it shall be, if thou do at all forget the LORD thy God, and walk after other gods, and serve them, and worship them, I testify against you this day that ye shall surely perish.

If you live like sinners, you will die like sinners. "Where, then, is the perseverance of the saints?" asks one. The answer lies in this: they will not live like sinners! God's grace will not let them go wandering after idols, to worship and to serve them. He will keep us faithful to himself; but if we wander after idol gods, it proves that we are not the Lord's true Israel, and we must expect to be treated as others have been who have turned aside to worship idols.
