The wrath of the Lord will not be turned back till he has done, till he has put into effect, the purposes of his heart: in days to come you will have full knowledge of this.
But give attention to yourselves, for fear that your hearts become over-full of the pleasures of food and wine, and the cares of this life, and that day may come on you suddenly, and take you as in a net:
That you may not be moved in mind or troubled by a spirit, or by a word, or by a letter as from us, with the suggestion that the day of the Lord is even now come;
But the day of the Lord will come like a thief; and in that day the heavens will be rolled up with a great noise, and the substance of the earth will be changed by violent heat, and the world and everything in it will be burned up.
Keep in mind, then, the teaching which was given to you, and be ruled by it and have a change of heart. If then you do not keep watch, I will come like a thief, and you will have no knowledge of the hour when I will come on you.
