Mount Sinai was covered with smoke because the LORD had come down in a flaming fire. Smoke poured out of the mountain just like a furnace, and the whole mountain shook.
Look closely at the sky! Stare at the earth. The sky will vanish like smoke; the earth will wear out like clothes. Everyone on this earth will die like flies. But my victory will last; my saving power never ends.
From the heart of Jerusalem the LORD roars like a lion, shaking the earth and sky. But the LORD is a fortress, a place of safety for his people Israel.
Straight after those days of suffering, “The sun will become dark, and the moon will no longer shine. The stars will fall, and the powers in the sky will be shaken.”
The day of the Lord's return will surprise us like a thief. The heavens will disappear with a loud noise, and the heat will melt the whole universe. Then the earth and everything on it will be seen for what they are.
