God had placed His people in Canaan as a mighty breastwork to stay the tide of moral evil, that it might not flood the world. If faithful to Him, God intended that Israel should go on conquering and to conquer. He would give into their hands nations greater and more powerful than the Canaanites. The promise was: “If ye shall diligently keep all these commandments which I command you, ... then will the Lord drive out all these nations from before you, and ye shall possess greater nations and mightier than yourselves. Every place whereon the soles of your feet shall tread shall be yours: from the wilderness and Lebanon, from the river, the river Euphrates, even unto the uttermost sea shall your coast be. There shall no man be able to stand before you: for the Lord your God shall lay the fear of you and the dread of you upon all the land that ye shall tread upon, as He hath said unto you.” Deuteronomy 11:22-25. (PP 544.1) MC VC

But regardless of their high destiny, they chose the course of ease and self-indulgence; they let slip their opportunities for completing the conquest of the land; and for many generations they were afflicted by the remnant of these idolatrous peoples, that were, as the prophet had foretold, as “pricks” in their eyes, and as “thorns” in their sides. Numbers 33:55. (PP 544.2) MC VC

The Israelites were “mingled among the heathen, and learned their works.” Psalm 106:35. They intermarried with the Canaanites, and idolatry spread like a plague throughout the land. “They served their idols: which were a snare unto them. Yea, they sacrificed their sons and their daughters unto devils: ... and the land was polluted with blood.... Therefore was the wrath of the Lord kindled against His people, insomuch that He abhorred His own inheritance.” Psalm 106:36-40. (PP 544.3) MC VC

Until the generation that had received instruction from Joshua became extinct, idolatry made little headway; but the parents had prepared the way for the apostasy of their children. The disregard of the Lord’s restrictions on the part of those who came in possession of Canaan sowed seed of evil that continued to bring forth bitter fruit for many generations. The simple habits of the Hebrews had secured them physical health; but association with the heathen led to the indulgence of appetite and passion, which gradually lessened physical strength and enfeebled the mental and moral powers. By their sins the Israelites were separated from God; His strength was removed from them, and they could no longer prevail against their enemies. Thus they were brought into subjection to the very nations that through God they might have subdued. (PP 544.4) MC VC
