I don't believe any pastor who is wealthy is wrong. Money is not the root of all evil, love of money is, as long as they don't get wealthy from the tithings I don't think it's wrong. Some are called to make money in business and give, but I believe we should pray for those who keep the tithings for themselves, since I saw a very disturbing NDE of someone.
We can all look at those millionair preachers with a private jet, but compared to an African I'm extremely wealthy and a car is luxury. I can take a bike or a bus and no tv and give the money to the Africans. I love what Smith Wigglesworth did. He worked as a plumber 60 hours a week next to his job as a preacher to feed the poor.
1 Timothy 6
(the instruction is not to sell everything like the rich guy)
