²⁵ See to it that you don’t resist the one who is speaking. If the people didn’t escape when they refused to listen to the one who warned them on earth, how will we escape if we reject the one who is warning from heaven? ²⁶ His voice shook the earth then, but now he has made a promise: Still once more I will shake not only the earth but heaven also.^{[a] 27} The words “still once more” reveal the removal of what is shaken—the things that are part of this creation—so that what isn’t shaken will remain. ²⁸ Therefore, since we are receiving a kingdom that can’t be shaken, let’s continue to express our gratitude.^[b] With this gratitude, let’s serve^[c] in a way that is pleasing to God with respect and awe, ²⁹ because our God really is a consuming fire.
