Revelation 2:2-4

2I know your works, your labor, and your endurance, and that you cannot tolerate evil people. You have tested those who call themselves apostles and are not, and you have found them to be liars.

3I know that you have persevered and endured hardships for the sake of my name, and you have not grown weary.

4But I have this against you: You have abandoned the love you had at first.
