Christians are to pursue peace and holiness, and to avoid roots of bitterness. We have come to Zion, not Sinai; we must listen to God and be thankful for receiving an unshakable Kingdom!
Looking carefully lest there be any man that falleth short of the grace of God; lest any root of bitterness springing up trouble you, and thereby the many be defiled; lest there be any fornication, or profane person, as Esau, who for one mess of meat sold his own birthright. For ye know that even when he afterward desired to inherit the blessing, he was rejected; for he found no place for a change of mind in his father, though he sought it diligently with tears. For ye are not come unto a mount that might be touched, and that burned with fire, and unto blackness, and darkness, and tempest, and the sound of a trumpet, and the voice of words; which voice they that heard entreated that no word more should be spoken unto them; for they could not endure that which was enjoined, If even a beast touch the mountain, it shall be stoned; and so fearful was the appearance, that Moses said,
“I exceedingly fear and quake:”
But ye are come unto mount Zion, and unto the city of the living God, the heavenly Jerusalem, and to innumerable hosts of angels, to the general assembly and church of the firstborn who are enrolled in heaven, and to God the Judge of all, and to the spirits of just men made perfect, and to Jesus the mediator of a new covenant, and to the blood of sprinkling that speaketh better than that of Abel. See that ye refuse not him that speaketh. For if they escaped not when they refused him that warned them on earth, much more shall not we escape who turn away from him that warneth from heaven: whose voice then shook the earth: but now he hath promised, saying,
“Yet once more will I make to tremble not the earth only, but also the heaven.”
And this word, Yet once more, signifieth the removing of those things that are shaken, as of things that have been made, that those things which are not shaken may remain. Wherefore, receiving a kingdom that cannot be shaken, let us have grace, whereby we may offer service well-pleasing to God with reverence and awe: for our God is a consuming fire (Hebrews 12:15-29).
