Hebrews 12:25-29 J.B. Phillips New Testament (PHILLIPS)
25-26 So be sure you do not refuse to hear the voice of God! For if they who refused to hear those who spoke to them on earth did not escape, how little chance of escape is there for us if we refuse to hear the one who speaks from Heaven. Then his voice shook the earth, but now he promises: ‘Yet once more I shake not only the earth, but also heaven’.
27-29 This means that in this final “shaking” all that is impermanent will be removed, that is, everything that is merely “made”, and only the unshakeable things will remain. Since then we have been given a kingdom that is “unshakeable”, let us serve God with thankfulness in the ways which please him, but always with reverence and holy fear. For it is perfectly true that our ‘God is a burning fire’.
