Revelation 3:4-6

3:4 But you have a few individuals in Sardis who have not stained their clothes, and they will walk with me dressed in white, because they are worthy. 3:5 The one who conquers will be dressed like them in white clothing, and I will never erase his name from the book of life, but will declare his name before my Father and before his angels. 3:6 The one who has an ear had better hear what the Spirit says to the churches.’
