"The Bible speaks against the sin of coventousness in the strongest terms possible. Without your being sanctified by the Savior, covetousness will keep you out of heaven (Rom. 1:28-29; 1 Cor. 6:9-11). Covetousness is idolatry (Eph. 5:5). . . Contentment and covetousness are opposites. Covetousness says, 'I need that. I won't be happy without it. It isn't fair; I don't have it. I want that more than anything else.' Contentment says, 'I have what I need. I am happy in the Lord. He does good to all. I wnat nothing more than I have.' So if you aren't content, you're almost certain coveting. . . Mercifully, this section on the Ten Commandments ends with a realistic appraisal of our ability to obey the commandents. . . " Kevin DeYoung. The Good News We Almost Forgot. 208.

Question 113: What is God's will for us in the Tenth Commandment?

Answer: That not even the slightest thought or desire contrary to any of God's Commandments should ever arise in my heart. Rather, with all my heart I should always hate sin and take pleasure in whatever is right.

Question 114: But can those coverted to God obey these commandments perfectly?

Answer: No. In this life even the holiest have only a small beginning of this obedience. Nevertheless, with all seriousness of purpose, they do begin to live according to all, not only some, of God's commandments.

Question 115: No one in this life can obey the Ten Commandments perfectly: Why then does God want them preached so pointedly?

Answer: First, so that the longer we live the more we may come to know our sinfulness and the more eagerly look to Christ for forgiveness of sins and righteousness. Second, so that, while praying to God for the grace of the Holy Spirit, we may never stop striving to be renewed more and more after God's image, until after this life reaches our goal: perfection.
