The Bookend of the Decalogue: Thou Shalt Not Covet
Why do I mention this? Because, this week's content is markedly different. It struck me as I was driving today: Paul encapsulates the whole Law in this on commandment as illustrates the Law, Sin, Faith, and Forgiveness in Romans 7. "Indeed I would not have known what sin was except through the law. For I would not have known what coveting really was if the law had not said, 'Do not covet'" (Romans 7:7). There must be something to this. Paul had so many other sins he could have illustrated, but he chose covetousness. Why?
This final commandment in the Decalogue against a covetous heart really book-ends the set of commandments that precede it. It's a summary command, but also an expansion upon the previous so-called "social" commandments. Whereas Paul may have been able to keep his body from outwardly stealing and murdering, he recognized that the tenth commandment made all of God's statutes an issue of the heart, not merely actions themselves.
Why is God so concerned about the attitude of our heart--and, particularly, the desires of our heart? Covetousness is simply a desire for one item/person or another. God knows, and indeed created us so that our desires play a major role in governing all the rest of our being. Our obedience, our worship, our love, our devotion, our acts of service, our everyday behavior--all of these find their root cause in the overpowering sense of desire within each of us. Likewise, adultery, murder, lust, stealing, lying, divorce, abortion, selfishness--all find their root cause in the overpowering sense of desire within us as well.
[As an aside, this makes for great fodder for discussion on the subject of compatibilism]
God gives strict warning in His law--not only in the Decalogue, but all throughout the Law--that Israel should guard their hearts and be mindful of their desires. A covetous person is no longer master over his/her desires. The tempter can exercise control over this person with disastrous consequences. It is for this reason that God commands His people: you shall not covet..."
"O LORD, God of our fathers Abraham, Isaac and Israel, keep this desire in the hearts of your people forever, and keep their hearts loyal to you." -- 1 Chronicles 29:18
