Isaiah 2:19 “And people shall enter the caves of the rocks And the holes of the ground, from before the terror of the Lord, And from the splendor of His majesty, when He rises to terrify the earth.”
We often hear the fear of God taught as “reverential awe,” and for Christians I think I understand why. The redeemed no longer fear judgement because we abide in God and His perfect love has cast out all fear of punishment (1John 4:16-18). But the same cannot be said of all those who are without Christ, for all who have not called on His name have the wrath of God abiding on them (John 3:36). To tell an unbeliever that the definition of fearing God is to stand in awe is a weakened and partial truth.
