If you wrote a book, are you entitled to profits? Joel Osteen wrote "Your Best Life Now" and because of the royalties, he no longer accepts a salary from the Church he pastors which happens to be the largest in America (Lakewood in Houston). God wants to live life abundantly. That includes all Christians, not just congegration members. Writing books is something they do on their own time.So what if God blesses them with a num ber one best seller. If anything, they are preaching thru these books to millions.
I am not judging mega churches, merely saying that people need to really study what they are trying to do, and what they actually teach. Some are cults, some don't even teach the Bible, some are there for entertainment purposes only, and some are merely blindly following other successful pastors by growing numbers, not winning souls. I never accept teaching until I have fully researched it. The person who earlier said that they "felt like it was a cult" experienced what we refer to as discernment.
