Judgment is certainly coming!
Isaiah put it like this (please read this slowly and prayerfully):
See, the LORD is going to lay waste the earth and devastate it; he will ruin its face and scatter its inhabitants– it will be the same for priest as for people, for the master as for his servant, for the mistress as for her servant, for seller as for buyer, for borrower as for lender, for debtor as for creditor. The earth will be completely laid waste and totally plundered. The LORD has spoken this word. The earth dries up and withers, the world languishes and withers, the heavens languish with the earth. The earth is defiled by its people; they have disobeyed the laws, violated the statutes and broken the everlasting covenant. Therefore a curse consumes the earth; its people must bear their guilt. Therefore earth’s inhabitants are burned up, and very few are left (Isaiah 24:1-6).
Even if we understand that the prophets sometimes spoke in hyperbolic language, the overall meaning of these words is undeniable: one day severe judgment will fall on a guilty planet.
Yet even in the midst of this terrifying description, there are words of hope for God’s people. In fact, there is a divine invitation to take refuge in Him:
Go, my people, enter your rooms and shut the doors behind you; hide yourselves for a little while until his wrath has passed by. See, the LORD is coming out of his dwelling to punish the people of the earth for their sins. The earth will disclose the blood shed on it; the earth will conceal its slain no longer (Isaiah 26:20-21).
As Proverbs states, “The name of the LORD is a fortified tower; the righteous run to it and are safe” (Proverbs 18:10). And as Psalm 91 declares, there is a place of protection, a hiding place, in God Most High. (See here for an exposition of the psalm in Hebrew.)
That’s why Jesus said this to His followers, immediately after warning of the judgment that would be coming to the earth: “When these things begin to take place, stand up and lift up your heads, because your redemption is drawing near” (Luke 21:28). The coming of the Lord is at hand.
And that’s why the very passage from Hebrews that we quoted at the beginning of this article ends with this: “Therefore, since we are receiving a kingdom that cannot be shaken, let us be thankful, and so worship God acceptably with reverence and awe, for our God is a consuming fire.'” (Hebrews 12:28-29)
The whole world will be shaken, but God’s kingdom — and God’s people — will not be shaken.
As the psalmist declared, “God is our refuge and strength, an ever-present help in trouble. Therefore we will not fear, though the earth give way and the mountains fall into the heart of the sea, though its waters roar and foam and the mountains quake with their surging. There is a river whose streams make glad the city of God, the holy place where the Most High dwells. God is within her, she will not fall; God will help her at break of day” (Psalm 46:1-5).
