Revelation 3:7-13 - The Letter To The Church In Philadelphia
7 "To the minister of the Church at Philadelphia write as follows: "'This is what the holy One and the true says--He who has the key of David--He who opens and no one shall shut, and shuts and no one shall open. 8 I know your doings. I have put an opened door in front of you, which no one can shut; because you have but a little power, and yet you have guarded My word and have not disowned Me. 9 I will cause some belonging to Satan's synagogue who say that they themselves are Jews, and are not, but are liars--I will make them come and fall at your feet and know for certain that I have loved you. 10 Because in spite of suffering you have guarded My word, I in turn will guard you from that hour of trial which is soon coming upon the whole world, to put to the test the inhabitants of the earth. 11 I am coming quickly: cling to that which you already possess, so that your wreath of victory be not taken away from you. 12 "'He who overcomes--I will make him a pillar in the sanctuary of My God, and he shall never go out from it again. And I will write on him the name of My God, and the name of the city of My God, the new Jerusalem, which is to come down out of Heaven from My God, and My own new name.
13 Let all who have ears give heed to what the Spirit is saying to the Churches.'
