So don’t turn a deaf ear to these gracious words. If those who ignored earthly warnings didn’t get away with it, what will happen to us if we turn our backs on heavenly warnings? His voice that time shook the earth to its foundations; this time—he’s told us this quite plainly—he’ll also rock the heavens: “One last shaking, from top to bottom, stem to stern.” The phrase “one last shaking” means a thorough housecleaning, getting rid of all the historical and religious junk so that the unshakable essentials stand clear and uncluttered.
Do you see what we’ve got? An unshakable kingdom! And do you see how thankful we must be? Not only thankful, but brimming with worship, deeply reverent before God. For God is not an indifferent bystander. He’s actively cleaning house, torching all that needs to burn, and he won’t quit until it’s all cleansed. God himself is Fire!
