+I. The guilt of forsaking the service of the Lord.+ 1. Man is bound by the law of his nature to obey that Almighty Being by whom he was made an intelligent and immortal creature. Every discovery which reason opens to him of the transcendent perfections of the Lord of the universe urges the duty of offering the homage of his heart and life. Every day's preservation increases his obligation to serve his gracious Preserver. 2. Many in forsaking the Lord violate their own express and solemn engagements (Heb. x. 29). +II. The folly of forsaking, &c.+ If we do so, we shall 1. incur the reproaches of our own mind; 2. forfeit the esteem and confidence of all good men; 3. forfeit the favour and incur the wrath of God. And for what are all those tremendous sacrifices made? For "the pleasures of sin," which are but "for a season"! +III. The danger of forsaking,+ &c.--"shall be consumed." The threatened doom is 1. awful, 2. certain.--_J. H. Hobart, D.D., Posthumous Works,_ ii. 220-229. THE DOOM OF THE APOSTATES. i. 28-31. _They that forsake the Lord shall be consumed. For they[1] shall be ashamed of the oaks which ye[1] have desired, and ye shall be confounded for the gardens that ye have chosen. For ye shall be as an oak whose leaf fadeth, and as a garden that hath no water. And the strong shall be as tow, and the maker of it as a spark, and they shall both burn together, and none shall quench them._ In modern days, when men "forsake the Lord," they become simply irreligious--practical atheists; but in ancient times such men became idolaters, they became worshippers of idols set up under the "oaks" planted on the hilltops, or in gardens.[2] It is almost impossible for us to understand the fascination of idol-worship, but it was very powerful, and the idols were made objects of passionate trust. They were regarded as the strength of those who served them. Trusting in their protection their votaries went forth confidently to battle. Defeat did not dispel this delusion; it was interpreted to mean merely that the god of the victors was mightier than the god of the vanquished. To men glorying in their protection, the prophet predicts utter destruction. You shall be consumed, he says; the day is at hand when ye shall be caused to blush for your gods; you yourselves shall be withered oaks, and gardens without water; yea, your idols, and ye who have made them, for they are but things, the work of your hands, shall be burned together in unquenchable fire.[3] The theme of these verses is therefore _the doom of the apostates, and the objects of their trust._
