Revelation 3:8-9

I know thy works (behold, I have set before thee a door opened, which none can shut), that thou hast a little power, and didst keep my word, and didst not deny my name. Behold, I give of the synagogue of Satan, of them that say they are Jews, and they are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.
