The world has a bias toward idolatry. The lost would never begin to believe that God could or would terrify. However, a little honest reading of Scripture will convince them that God is to be greatly feared. The apostle Paul said that it is knowledge of the terror of the Lord that should cause the Christian to persuade men and woman to flee to the Savior (see 2 Cor. 5:11).
Genesis 35:5 And they journeyed, and the terror of God was upon the cities that were all around them, and they did not pursue the sons of Jacob.
