Revelation 3:6

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.

⁶  He that hath an ear, let him hear what the Spirit saith unto the churches.

⁷  And to the angel of the church in Philadelphia write; These things saith he that is holy, he that is true, he that hath the key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth;

⁸  I know thy works: behold, I have set before thee an open door, and no man can shut it: for thou hast a little strength, and hast kept my word, and hast not denied my name.
