Revelation 3:7-13 - The Letter To The Church In Philadelphia

⁷ And to the angel of the church in Philadelphia write, These things says the Holy One, the True, he that has the key of David, he that opens and no one shall shut, and shuts and no one shall open, ⁸ I know your works; behold, I have placed before you an opened door, which no man can shut; because you have a little power, and kept my word, and did not deny my name. ⁹ Behold, I will make those of the synagogue of Satan who say they are Jews, and are not, but lie, behold, I will make them come and worship at your feet, and they shall know that I have loved you. ¹⁰ Because you have kept the word of my patience, I also will keep you from the hour of trial which is to come on all the world, to try those who dwell on the earth. ¹¹ I come quickly; keep what you have, that no man may take your crown. ¹² Him that overcomes will I make a pillar in the temple of my God, and he shall go out of it no more, and I will write on 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.

¹³ Let him that has an ear hear what the Spirit says to the churches.
