1 And unto the angel of the church in Sardis write;
  These things saith he that hath the seven Spirits of
  God, and the seven stars; I know thy works, that thou
  hast a name that thou livest, and art dead.
   2 Be watchful, and strengthen the things which
  remain, that are ready to die: for I have not found
  thy works perfect before God.
   3 Remember therefore how thou hast received and
  heard, and hold fast, and repent. If therefore thou
  shalt not watch, I will come on thee as a thief, and
  thou shalt not know what hour I will come upon thee.
   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.
   9 Behold, I will make them of the synagogue of
  Satan, which say they are Jews, and are not, but do
  lie; behold, I will make them to come and worship
  before thy feet, and to know that I have loved thee.
  10 Because thou hast kept the word of my patience, I
  also will keep thee from the hour of temptation,
  which shall come upon all the world, to try them that
  dwell upon the earth.
  11 Behold, I come quickly: hold that fast which thou
  hast, that no man take thy crown.
  12 Him that overcometh will I make a pillar in the
  temple of my God, and he shall go no more out: and I
  will write upon him the name of my God, and the name
  of the city of my God, which is new Jerusalem, which
  cometh down out of heaven from my God: and I will
  write upon him my new name.
  13 He that hath an ear, let him hear what the Spirit
  saith unto the churches.
  14 And unto the angel of the church of the Laodiceans
  write; These things saith the Amen, the faithful and
  true witness, the beginning of the creation of God;
  15 I know thy works, that thou art neither cold nor
  hot: I would thou wert cold or hot.
  16 So then because thou art lukewarm, and neither
  cold nor hot, I will spue thee out of my mouth.
  17 Because thou sayest, I am rich, and increased with
  goods, and have need of nothing; and knowest not that
  thou art wretched, and miserable, and poor, and
  blind, and naked:
  18 I counsel thee to buy of me gold tried in the
  fire, that thou mayest be rich; and white raiment,
  that thou mayest be clothed, and that the shame of
  thy nakedness do not appear; and anoint thine eyes
  with eyesalve, that thou mayest see.
  19 As many as I love, I rebuke and chasten: be
  zealous therefore, and repent.
  20 Behold, I stand at the door, and knock: if any man
  hear my voice, and open the door, I will come in to
  him, and will sup with him, and he with me.
  21 To him that overcometh will I grant to sit with me
  in my throne, even as I also overcame, and am set
  down with my Father in his throne.
  22 He that hath an ear, let him hear what the Spirit
  saith unto the churches.
