But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,
2 Peter 3:10-11 KJV
But when the Day of God’s Judgment does come, it will be unannounced, like a thief. The sky will collapse with a thunderous bang, everything disintegrating in a huge conflagration, earth and all its works exposed to the scrutiny of Judgment. Since everything here today might well be gone tomorrow, do you see how essential it is to live a holy life? Daily expect the Day of God, eager for its arrival. The galaxies will burn up and the elements melt down that day—but we’ll hardly notice. We’ll be looking the other way, ready for the promised new heavens and the promised new earth, all landscaped with righteousness.
2 Peter 3:10-11 MSG
