Rev. 3:7-13 – To the angel of the church in Philadelphia write: The Holy One, the True One, the One who has the key of David, who opens and no one will close, and closes and no one opens says: I know your works. Because you have limited strength, have kept My word, and have not denied My name, look, I have placed before you an open door that no one is able to close. Take note! I will make those from the synagogue of Satan, who claim to be Jews and are not, but are lying – note this – I will make them come and bow down at your feet, and they will know that I have loved you. Because you have kept My command to endure, I will also keep you from the hour of testing that is going to come over the whole world to test those who live on the earth. I am coming quickly. Hold on to what you have, so that no one takes your crown. The victor: I will make him a pillar in the sanctuary of My God, and he will never go out again. 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 Anyone who has an ear should listen to what the Spirit says to the churches.

Twenty-eight miles southeast of Sardis is Philadelphia, built by King Attalus Philadelphus of Pergamum. “Philadelphus” is similar to the Greek word philadelphia, meaning brotherly love, which occurs seven times in the New Testament. Known for its agricultural products, Philadelphia also is situated on a geological fault and therefore prone to earthquakes. In B.C. 17 a major earthquake destroys Philadelphia, Sardis and 10 other cities. Its location is crucial, however, as it sits on a main route from Rome to the East and therefore is called “the gateway to the East.” It also is known as “little Athens” because of its many pagan temples.
The city hosts one of only two churches – the other being Smyrna – for which Christ has nothing but unvarnished praise. While the city’s good name preceded the church, the believers in Philadelphia no doubt enhance its reputation because of their love of Christ and love for one another. “But it is not enough to love God and our fellow believers; we must also love a lost world and seek to reach unbelievers with the Good News of the Cross,” writes Warren Wiersbe. “This church had a vision to reach a lost world, and God set before them an open door.”
