25 See that you do not refuse him that speaks. For if those who refused him that spoke on earth did not escape, much less shall we escape, if we turn away from him that speaks from the heavens,
26 whose voice then shook the earth; but now he has promised, saying, Yet even once, I shall shake not the earth only, but also the heaven.
27 And this word, Yet even once, signifies the removing of those things that are shaken, as of things that are made, that those things which cannot be shaken may remain.
28 Therefore, receiving a kingdom which cannot be moved, let us hold fast to the grace, by which we serve God, pleasing him with reverence and godly fear:
29 for our God is a consuming fire.
