Earlier we considered four systems of ethics cultural relativism, situationism, behaviorism, and emotivism that in one way or another all self-destruct, ultimately destroyed by their own arbitrarily chosen principles. God's moral revelation is based on His nature. God is separate from everything that exists, is free of all imperfections and limitations, and is His own standard. No moral rule exists outside of Him. Holiness, goodness, and truthfulness indeed all biblical morality are rooted in the nature of God.
Man is a unique moral being .
The biblical picture of mankind differs strikingly from the humanistic versions of mankind. God's moral principles have historical continuity. If God's moral revelation is rooted in His nature, it is clear that those moral principles will transcend time. Although specific commands may change from one era to another, the principles remain constant. God's moral revelation has intrinsic value.
