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

⁷ "And to the angel of the church in Philadelphia write: 'These are the words of him who is holy, who is true, who has the key of David, who opens and no one shuts, and shuts and no one opens: ⁸ I know your works. See, I have set before you an open door, and no one can shut it. I know that you have little strength, yet you have kept my word, and have not denied my name. ⁹ Behold, I will make those of the synagogue of Satan who say that they are Jews and are not, but lielook, I will make them come and bow down before your feet, and know that I have loved you. ¹⁰ Because you have kept my command to persevere, I also will keep you from the hour of trial which shall come upon the whole world, to test those who dwell on the earth. ¹¹ I am coming soon; hold fast to what you have, so that no one may take your crown. ¹² He who overcomes, I will make him a pillar in the temple of my God, and he shall never go out of it. 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 I will write on him my new name.

¹³ He who has an ear, let him hear what the Spirit says to the churches.'
