Hebrews 12:25-29 NET
Take care not to refuse the one who is speaking! For if they did not escape when they refused the one who warned them on earth, how much less shall we, if we reject the one who warns from heaven? Then his voice shook the earth, but now he has promised, “ I will once more shake not only the earth but heaven too .” Now this phrase “ once more ” indicates the removal of what is shaken, that is, of created things, so that what is unshaken may remain. So since we are receiving an unshakable kingdom, let us give thanks, and through this let us offer worship pleasing to God in devotion and awe. For our God is indeed a devouring fire .
