Revelation 3:4-6

“Yet there are some in the church in Sardis who have not soiled their clothes with evil. They will walk with me in white, for they are worthy. All who are victorious will be clothed in white. I will never erase their names from the Book of Life, but I will announce before my Father and his angels that they are mine. “Anyone with ears to hear must listen to the Spirit and understand what he is saying to the churches.
