I know your doings. I have put an opened door in front of you, which no one can shut; because you have but a little power, and yet you have guarded My word and have not disowned Me.

The unclean are shut out, and so are all who practise magic, all fornicators, all murderers, and those who worship idols, and every one who loves falsehood and tells lies.
