Hebrews 12:25-27

Living Bible

²⁵ So see to it that you obey him who is speaking to you. For if the people of Israel did not escape when they refused to listen to Moses, the earthly messenger, how terrible our danger if we refuse to listen to God who speaks to us from heaven! ²⁶ When he spoke from Mount Sinai his voice shook the earth, but, “Next time,” he says, “I will not only shake the earth but the heavens too.” ²⁷ By this he means that he will sift out everything without solid foundations so that only unshakable things will be left.
