² So wake up, and strengthen what you still have before it dies completely. For I find that what you have done is not yet perfect in the sight of my God. ^3 (A)Remember, then, what you were taught and what you heard; obey it and turn from your sins. If you do not wake up, I will come upon you like a thief, and you will not even know the time when I will come. ⁴ But a few of you there in Sardis have kept your clothes clean. You will walk with me, clothed in white, because you are worthy to do so.
