Hebrews 12:14-17, 25-29

Work at living in peace with everyone, and work at living a holy life, for those who are not holy will not see the Lord. Look after each other so that none of you fails to receive the grace of God. Watch out that no poisonous root of bitterness grows up to trouble you, corrupting many. Make sure that no one is immoral or godless like Esau, who traded his birthright as the firstborn son for a single meal. You know that afterward, when he wanted his father’s blessing, he was rejected. It was too late for repentance, even though he begged with bitter tears.

Be careful that you do not refuse to listen to the One who is speaking. For if the people of Israel did not escape when they refused to listen to Moses, the earthly messenger, we will certainly not escape if we reject the One who speaks to us from heaven! When God spoke from Mount Sinai his voice shook the earth, but now he makes another promise: “Once again I will shake not only the earth but the heavens also.” This means that all of creation will be shaken and removed, so that only unshakable things will remain. Since we are receiving a Kingdom that is unshakable, let us be thankful and please God by worshiping him with holy fear and awe. For our God is a devouring fire.
