The Promise to the Church of Sardis

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. He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name of the Book of Life, but I will confess his name before My Father and before His angels. He that hath an ear, let him hear what the Spirit saith unto the Churches.
