Revelation 3:7-8 NIVUK
‘To the angel of the church in Philadelphia write: These are the words of him who is holy and true, who holds the key of David. What he opens no-one can shut, and what he shuts no-one can open. I know your deeds. See, I have placed before you an open door that no-one can shut. I know that you have little strength, yet you have kept my word and have not denied my name.
