Every creature under heaven should be concerned about his or her duty to the almighty Creator and judge of all the earth. Therefore, the question What duty does the Creator require of creatures? is always relevant. The biblical answer is that requires personal, perfect, perpetual obedience to His revealed will. The next logical question is Where do we find God’s revealed will regarding moral conduct? The biblical answer is that it is summarized in the Ten Commandments…
…The commandments demand both external and internal obedience. Addressing the will and the heart, as well as actions, they require more than merely outward conformity. They also require inward affection. The commandments forbid not only evil acts but evil desires and inclinations. They go to the mind—including the will and the affections….thereby calling for obedience from the whole man…Not only murder, but hate. Not only adultery, but lusting. Not only stealing, but coveting.
