God gave man Ten Commandments. Every one of them is vital, in all ages. For only by observing them can man live a full life each week; maintain a happy marriage; and function well in his home, his job, and even in the world internationally.
God Himself is the Root of the Moral Law, and perfectly reflects it. Salvation was never by the works of the Law. For even before the fall, man was to keep it out of gratitude for God's great grace. Unfallen man kept the whole Decalogue. The Sabbath, Marriage, the Forbidden Fruit, and the Tree of Life all reveal it. When man broke God's Law, he degenerated more and more--from the Fall to the Flood. The Patriarchs kept it, and the Prophets called man back to keep it. So, too, should we.
