Hebrews 12:22-29

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.
