Revelation 3:6-8

6He who has an ear, let him hear what the Ruach is saying to Messiah’s communities.

7To the angel of Messiah’s community in Philadelphia write: “Thus says the Holy One, the True One, who has the key of David, who opens and no one will shut, and who shuts and no one opens:

8I know your deeds. Behold, I have set before you an open door that no one is able to shut—because you have little power, but you have kept My word and have not denied My name.
