Revelation 3 

"And to the angel of the church in Sardis write: He who has the seven Spirits of God, and the seven stars, says this: 'I know your deeds, that you have a name that you are alive, but you are dead. "Wake up, and strengthen the things that remain, which were about to die; for I have not found your deeds completed in the sight of My God. 'Remember therefore what you have received and heard; and keep it, and repent. If therefore you will not wake up, I will come like a thief, and you will not know at what hour I will come upon you. 'But you have a few people in Sardis who have not soiled their garments; and they will walk with Me in white; for they are worthy. 'He who overcomes shall thus be clothed in white garments; and I will not erase his name from the book of life, and I will confess his name before My Father, and before His angels. 'He who has an ear, let him hear what the Spirit says to the churches.' "And to the angel of the church in Philadelphia write: He who is holy, who is true, who has the key of David, who opens and no one will shut, and who shuts and no one opens, says this: 'I know your deeds. Behold, I have put before you an open door which no one can shut, because you have a little power, and have kept My word, and have not denied My name. 'Behold, I will cause those of the synagogue of Satan, who say that they are Jews, and are not, but lie -- behold, I will make them to come and bow down at your feet, and to know that I have loved you. 'Because you have kept the word of My perseverance, I also will keep you from the hour of testing, that hour which is about to come upon the whole world, to test those who dwell upon the earth. 'I am coming quickly; hold fast what you have, in order that no one take your crown. 'He who overcomes, I will make him a pillar in the temple of My God, and he will not go out from it anymore; and I will write upon him the name of My God, and the name of the city of My God, the new Jerusalem, which comes down out of heaven from My God, and My new name. 'He who has an ear, let him hear what the Spirit says to the churches.' "And to the angel of the church in Laodicea write: The Amen, the faithful and true Witness, the Beginning of the creation of God, says this: 'I know your deeds, that you are neither cold nor hot; I would that you were cold or hot. 'So because you are lukewarm, and neither hot nor cold, I will spit you out of My mouth. 'Because you say, "I am rich, and have become wealthy, and have need of nothing," and you do not know that you are wretched and miserable and poor and blind and naked, I advise you to buy from Me gold refined by fire, that you may become rich, and white garments, that you may clothe yourself, and that the shame of your nakedness may not be revealed; and eyesalve to anoint your eyes, that you may see. 'Those whom I love, I reprove and discipline; be zealous therefore, and repent. 'Behold, I stand at the door and knock; if anyone hears My voice and opens the door, I will come in to him, and will dine with him, and he with Me. 'He who overcomes, I will grant to him to sit down with Me on My throne, as I also overcame and sat down with My Father on His throne. 'He who has an ear, let him hear what the Spirit says to the churches.'"
