kjv@Revelation:3:7@ And to the angel of the church in Philadelphiawrite; These things saith he that is holy, he that is true, he that hath the key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth;
Philadelphia on the other hand is a church that will be kept from the hour of temptation that the earth will suffer. They are being opposed by a temple of Satan hiding under the cover of some Jews yet have exhibited strength, kept His word (of patience), and not denied His name. Notice how none of these churches have it easy, but, some hold fast, hold true, gain the Lord's strength and overcome.
