Revelation 2:3-5 (New International Version)

³You have persevered and have endured hardships for my name, and have not grown weary. ⁴Yet I hold this against you: You have forsaken your first love. ⁵Remember the height from which you have fallen! Repent and do the things you did at first. If you do not repent, I will come to you and remove your lampstand from its place.
