Hebrews 12:25-29

25See to it that you do not refuse the One who is speaking! For if they did not escape when they refused the One who was warning them on earth, much less will we escape if we reject the One who warns us from heaven.

26His voice shook the earth then, but now He has promised, saying, “Yet once more I will shake not only the earth, but also the heavens.”

27Now this phrase, “Yet once more,” shows the removal of those things that are shaken—that is, created things—so that what cannot be shaken may remain.

28Therefore, since we are receiving a kingdom that cannot be shaken, let us show gratitude—through this we may offer worship in a manner pleasing to God, with reverence and awe.

29For our God is a consuming fire.
