10But the day of the Lord will come like a thief. On that day the heavens will pass away with a dreadful noise, the elements will be consumed by fire, and the earth and all the works done on it will be exposed. 11Since everything will be destroyed in this way, what sort of people ought you to be? You must live holy and godly lives, 12waiting for and hastening the coming day of God. Because of that day, the heavens will be destroyed by fire and the elements will melt away in the flames.
