Hebrews 12:25-27 New Life Version (NLV)
25 Be sure you listen to the One Who is speaking to you. The Jews did not obey when God’s Law was given to them on earth. They did not go free. They were punished. We will be punished more if we do not listen to God as He speaks from heaven. 26 On Mount Sinai, God’s voice shook the earth. But now He has promised, saying, “Once more I will shake the earth and the heavens.”
27 When God says, “Once more,” He means He will take away everything of this world that can be shaken so the things that cannot be shaken will be left.
