See that you refuse not Him that speaks. For if they escaped not who refused Him that spoke on earth, much more shall we not escape, if we turn away from Him that speaks from heaven: Whose voice then shook the earth: but now He has promised, saying, Yet once more I shake not the earth only, but also heaven. And this word, Yet once more, signifies the removing of those things that are shaken, as of things that are made, that those things which cannot be shaken may remain. Therefore we receiving a kingdom which cannot be moved, let us have grace, by which we may serve God acceptably with reverence and godly fear: For our God is a consuming fire. (Hebrews 12:25-29)
