Revelation 2:3-6

and you have persevered and have patience, and have labored for My name’s sake and have not become weary. Nevertheless I have this against you, that you have left your first love. Remember therefore from where you have fallen; repent and do the first works, or else I will come to you quickly and remove your lampstand from its place—unless you repent. But this you have, that you hate the deeds of the Nicolaitans, which I also hate.
