Revelation 2:3-5

I am also aware that you have persisted steadfastly, endured much for the sake of my name, and have not grown weary. But I have this against you: You have departed from your first love! Therefore, remember from what high state you have fallen and repent! Do the deeds you did at the first; if not, I will come to you and remove your lampstand from its place – that is, if you do not repent.
