But the day of the Lord will come like a thief, in which the heavens will pass away with a roar and the elements will be destroyed with intense heat, and the earth and its works will be discovered.
(“Behold, I am coming like a thief. Blessed is the one who stays awake and keeps his clothes, so that he will not walk about naked and people will not see his shame.”)
So remember what you have received and heard; and keep it, and repent. Then if you are not alert, I will come like a thief, and you will not know at what hour I will come to you.
