“Fear” (3374) of God is natural. Human beings are not equipped to feel comfortable around the divine or the eternal. Think of the general reaction to angels appearing: fear. Remember Isaiah’s response to being in the presence of God.
(Isaiah 6:5 KJV) Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the LORD of hosts.I imagine that even a rebellious unbeliever would quail in the presence of God. Swagger would dissolve into knees of jelly. There would be an unavoidable awareness of the gulf between a holy Creator and a sinful creature.
That is not true for believers because through the blood of Christ we have been enabled to approach the throne with boldness. At times we get a little too cocky and familiar. It is important that we have the fear brought back to its healthy balance.
So? Fear enough to be in reverence. Fear enough to be in awe. It will open the gate to His presence. Most of us will be like the shepherds in the field more than the wise men coming from afar.
