Philadelphia, also known as Alasehir, was a Lydian city founded between 159-138 B.C. by Attalus II Philadelphus of Pergamum. In commemoration of the king's love and loyalty for his brother Eumenes II, the city was called Philadelphia, which in Greek meant "city of brotherly love". The ancient city is perhaps most famous as the location of one of The Seven Churches Of Revelation.
The city is located in Asia Minor, today southwestern Turkey. Built on an elevated terrace, the city overlooked the nearby Hermus Valley, in which ran a Persian Royal Road.
The area is very susceptible to earthquakes (see Earthquake!), and in 17 A.D. the city was completely devastated. Apparently right above the fault line, the city continued to be severely shaken by periodic aftershocks for another 20 years after the great quake.
And just what did Jesus Christ (Revelation 1:1) prophesy (see Bible Prophecy) about the ancient city through The Apostle John while he was on Patmos?
"And to the angel of the church in Philadelphia write:"
"'The words of the Holy One, the True One, Who has the key of David, Who opens and no one shall shut, Who shuts and no one opens. I know your works [see Believers]. Behold, I have set before you an open door, which no one is able to shut; I know that you have but little power, and yet you have kept My Word and have not denied My Name. Behold, I will make those of the synagogue of Satan who say that they are Jews and are not, but lie - behold, I will make them come and bow down before your feet, and learn that I have loved you. Because you have kept My Word of patient endurance, I will keep you from the hour of trial which is coming on the whole world, to try those who dwell upon the earth."
"I am coming soon [see The Return Of Jesus Christ]; hold fast what you have, so that no one may seize your crown. He who conquers, I will make him a pillar in the temple of my God [see Physical and Spiritual Temples]; never shall he 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 [see The City To Come and The Capital City] which comes down from My God out of heaven, and My own new Name. He who has an ear, let him hear what the Spirit says to the churches.'" (Revelation 3:7-13 RSV)
Fact Finder: Is the earth going experience another "flood," after Jesus Christ has ruled the earth for 1,000 years after His return, and before God and the New Jerusalem arrive?
