But the day when the Lord comes again will surprise everyone like the coming of a thief. The sky will disappear with a loud noise. Everything in the sky will be destroyed with fire. And the earth and everything in it will be burned up.
“Right after the trouble of those days, this will happen: ‘The sun will become dark, and the moon will not give light. The stars will fall from the sky, and everything in the sky will be changed.’
The Lord God will shout from Zion. He will shout from Jerusalem, and the sky and the earth will shake. But the Lord God will be a safe place for his people. He will be a place of safety for the people of Israel.
Look up to the heavens! Look around you at the earth below! The skies will disappear like clouds of smoke. The earth will become like worthless old clothes. The people on earth will die, but my salvation will continue forever. My goodness will never end.
Mount Sinai was covered with smoke. Smoke rose off the mountain like smoke from a furnace. This happened because the Lord came down to the mountain in fire. Also the whole mountain began to shake.
