Church Of Philadelphia

Revelation 3:7 (ESV)

To the Church in Philadelphia

“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 will shut, who shuts and no one opens.

Revelation 3:12-13 (ESV)

12 The one who conquers, I will make him a pillar in the temple of my God. 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, which comes down from my God out of heaven, and my own new name. 13 He who has an ear, let him hear what the Spirit says to the churches.

The holy and true one is Jesus. He is the Holy Son of God and is the way, truth, and the life of the Father. It is He who opened the door of heaven and He alone will shut the door. 

That door leads to the new Jerusalem and the Bride of Christ who bears His name and becomes the living temple of God because He dwells in us.
