Revelation 2:3-6

and you have perseverance and have endured for My name’s sake, and have not grown weary. But I have this against you, that you have left your first love. Therefore remember from where you have fallen, and repent and do the deeds you did at first; or else I am coming to you and will remove your lampstand out of its place—unless you repent. Yet this you do have, that you hate the deeds of the Nicolaitans, which I also hate.
