In your letter you asked me about food offered to idols. All of us know something about this subject. But knowledge makes us proud of ourselves, while love makes us helpful to others.
I know everything you have done, including your hard work and how you have endured. I know you won't put up with anyone who is evil. When some people pretended to be apostles, you tested them and found out that they were liars.
You claim to be rich and successful and to have everything you need. But you don't know how badly off you are. You are pitiful, poor, blind, and naked.
