Proposition: God who is both your Lord and Savior has the right to command you to obey His every word.
Sermon Outline: I. The divine ORIGIN of the Ten Commandments (v. 1). II. The divine AUTHORITY of the Ten Commandments (v. 2).

When Moses first approached Pharaoh to let God people go, Pharaoh's defiant response was "Who is that Lord that I should obey His voice to let Israel go?" (Exodus 5:1-2). Well, ten plagues later and Pharaoh's army drowned and dead on the shore of the Red Sea, God had provided a thorough answer to Pharaoh's initial question (Exodus 14:30-31).
