Make very sure that you never refuse to listen to God when he speaks! For the God who Spoke on earth from Sinai is the same God who now speaks from heaven. Those who heard him speak his living Word on earth found nowhere to hide, so what chance is there for us to escape if we turn our backs on God and refuse to hear his warnings as he speaks from heaven?
The earth was rocked at the sound of his voice from the mountain, but now he has promised. “Once and for all, I will not only shake the systems of the world, but also the unseen powers in the heavenly realm!”
Now this phrase “once and for all, clearly indicates the final removal of things that are shaking, that is, the old order, so only what is unshakeable will remain. Since we are receiving our rights to an unshakeable kingdom we should be extremely thankful and offer God the purest worship that delights his heart as we lay down our lives in absolute surrender, filled with awe. For our, God is a holy, devouring fire!
