Revelation 3:7 - 3:8
To the Church in Philadelphia
7 “And to the angel of the church in Philadelphia write: This is what He who is holy, who is true, who has the key of David, who opens and no one will shut, and who shuts and no one opens, says: 8 ‘I know your deeds. Behold, I have given before you an open door which no one can shut, because you have a little power, and have kept My word, and have not denied My name.
