Revelation 3:4-6

⁴But thou hast a few names in Sardis which have not defiled their garments, and they shall walk with me in white, because they are worthy.

⁵He that overcomes, he shall be clothed in white garments, and I will not blot his name out of the book of life, and will confess his name before my Father and before his angels.

⁶He that has an ear, let him hear what the Spirit says to the assemblies.
