Revelation 3:6-8

“Let anyone who has ears to hear listen to what the Spirit says to the churches. “Write to the angel of the church in Philadelphia: Thus says the Holy One, the true one, the one who has the key of David, who opens and no one will close, and who closes and no one opens: I know your works. Look, I have placed before you an open door that no one can close because you have but little power; yet you have kept my word and have not denied my name.
