Revelation 3:4-5

King James Version

⁴ Thou hast a few names even in Sardis which have not defiled their garments; and they shall walk with me in white: for they are worthy.

⁵ He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.
