Hebrews 12:24-27

and to Jesus, the Mediator of a new covenant [uniting God and man], and to the sprinkled blood, which speaks [of mercy], a better and nobler and more gracious message than the blood of Abel [which cried out for vengeance]. [Gen 4:10] See to it that you do not refuse [to listen to] Him who is speaking [to you now]. For if those [sons of Israel] did not escape when they refused [to listen to] him who warned them on earth [revealing God’s will], how much less will we escape if we turn our backs on Him who warns from heaven? [Heb 2:1-4] His voice shook the earth [at Mount Sinai] then, but now He has given a promise, saying, “YET ONCE MORE I WILL SHAKE NOT ONLY THE EARTH, BUT ALSO THE [starry] HEAVEN.” [Hag 2:6] Now this [expression], “Yet once more,” indicates the removal and final transformation of all those things which can be shaken—that is, of that which has been created—so that those things which cannot be shaken may remain. [Ps 102:26]
