The central message of the sermon is that true worship must be centered on God's sovereign choice, not human preference or cultural imitation, as emphasized in Deuteronomy 12. It calls for the complete eradication of pagan worship practices—altars, pillars, groves, and idols—because God alone determines where His name is to be honored, first at Shiloh and later in Jerusalem. The passage establishes a clear contrast between the chaotic 'every man doing what is right in his own eyes' of the wilderness and the ordered, centralized worship God commands upon entering the Promised Land. This includes bringing all offerings, tithes, and sacrifices to the designated place, with special care for the Levites and the prohibition of eating blood, rooted in the sanctity of life and obedience to God's unchanging will. The sermon underscores the enduring principle that obedience to God's commands, without addition or subtraction, leads to blessing, while idolatry and self-reliance result in divine judgment, a warning echoed from the Old Testament through the New Testament's call to preserve the integrity of God's Word.
