Revelation 3:2-4

New Century Version

² Wake up! Strengthen what you have left before it dies completely. I have found that what you are doing is less than what my God wants. ³ So do not forget what you have received and heard. Obey it, and change your hearts and lives. So you must wake up, or I will come like a thief, and you will not know when I will come to you. ⁴ But you have a few there in Sardis who have kept their clothes unstained, so they will walk with me and will wear white clothes, because they are worthy.
