Revelation 3:6-10

He who has an ear, let him hear and heed what the Spirit says to the churches.’ “And to the angel (divine messenger) of the church in Philadelphia write: T hese are the words of the Holy One, the True One, He who has the key [to the house] of David, He who opens and no one will [be able to] shut, and He who shuts and no one opens: [Is 22:22] ‘I know your deeds. See, I have set before you an open door which no one is able to shut, for you have a little power, and have kept My word, and have not renounced or denied My name. [1 Cor 16:9; Col 4:3, 4] Take note, I will make those of the synagogue of Satan, who say that they are Jews and are not, but lie—I will make them come and bow down at your feet and make them know [without any doubt] that I have loved you. [Is 45:14; 49:23; 60:14] Because you have kept the word of My endurance [My command to persevere], I will keep you [safe] from the hour of trial, that hour which is about to come on the whole [inhabited] world, to test those who live on the earth. [Mark 13:9; 2 Thess 2:1-12]
