Revelation 3:4-6

But thou hast a few names in Sardis that did not defile their garments: and they shall walk with me in white; for they are worthy. He that overcometh shall thus be arrayed in white garments; and I will in no wise blot his name out of the book of life, and I will confess his name before my Father, and before his angels. He that hath an ear, let him hear what the Spirit saith to the churches.
