In Context

26 Whose voice then shook the earth: but now he has promised, saying, Yet once more I shake not the earth only, but also heaven.

27 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.

28 Why we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear:

29 For our God is a consuming fire.
