Hebrews 12:25-27 Evangelical Heritage Version (EHV)
25 See to it that you do not refuse to listen to the one who is speaking. For if those people did not escape when they refused to listen to the one who spoke God’s message on earth, how much less likely is it that we will escape, if we turn away from the one who spoke God’s message to us from heaven? 26 At that time his voice shook the earth, but now he has promised, “Once more I will shake not only the earth but also heaven.”[a]
27 The words “once more” clearly indicate the removal of the things that are being shaken, that is, the things that have been made, so that the things that cannot be shaken remain permanently.
