Did Jesus demand we obey the Ten Commandments? The word commandments does not mean the Ten Commandments alone. It means all God’s commandments. Deuteronomy expands the Ten Commandments with many more commandments. Nobody keeps the Ten Commandments in the letter, not even those who practice the original Sabbath day. If they did, they would put to death idolaters, Sabbath breakers, adulterers and those who dishonor their parents as the letter of the law demands. Jesus explained how we keep the spirit of the law in the Sermon on the Mount. Christians fulfill the law in spirit not the letter. The letter kills, but the spirit gives life (2 Corinthians 3:6).
