 If you ever get on social media, you'll see Christians selling books, selling magazines, selling memberships, trying to raise money, paying for going. You actually have to pay to go to a conference to hear some celebrity talk about how he loves Jesus. I've seen singers sell their music at revivals. I've seen preachers sell their books in the foyer of the church, and they all believed it was okay to do that. It is not okay to sell merchandise at church.
