If you’ve ever been in a severe thunderstorm you know how loud the claps of thunder can be…especially if a flash of lightning strikes very close by. This verse likens that deafening crash with the voice of God and His display of power…doing things far beyond the boundaries of human comprehension. This greatness of God that is too wonderful for us to understand is best summed up in Job 11:7-9 when they ask, “Can you fathom the mysteries of God? Can you probe the limits of the Almighty?” The answer is no…God’s power is outside the reach of our minds.
