Revelation 3:3 "Remember, then, what you received and heard. Keep it, and repent. If you will not wake up, I will come upon you like a thief, and you will not know at what hour I will come against you."

Revelation 16:15 “Look, I come like a thief! Blessed is the one who stays awake and remains clothed, so as not to go naked and be shamefully exposed.”
