At Mount Sinai, God did something He did for no other nation and no other law code: He spoke the Ten Commandments audibly and wrote them with His own finger on tables of stone (Exodus 31:18). The Hebrew Bible calls them the "ten words" — the core covenant charter, set apart from the hundreds of civil and ceremonial regulations that surrounded them.
Notice how they begin — not with a demand but with a declaration of grace: "I am the LORD thy God, which have brought thee out of the land of Egypt, out of the house of bondage" (Exodus 20:2). Redemption comes first; commandments follow. God did not say, "Keep these rules and I will rescue you." He rescued His people and then showed them how redeemed people live. That order — grace, then law — is the same order the Christian lives in today.
Are the Ten Commandments still binding on Christians? The historic Protestant answer is yes — not as a ladder to climb into God's favor, but as the abiding moral law that reflects God's unchanging character. Nine of the ten are explicitly restated in the New Testament, and Jesus and the apostles treat the moral law as the standing description of love for God and neighbor.
