Revelation 2:2-5 NIV

[2] I know your deeds, your hard work and your perseverance. I know that you cannot tolerate wicked people, that you have tested those who claim to be apostles but are not, and have found them false. [3] You have persevered and have endured hardships for my name, and have not grown weary. [4] Yet I hold this against you: You have forsaken the love you had at first. [5] Consider how far 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.
