Yes, at least Billy preached the gospel when he preached!
But even Billy spoke like an inclusivist in interviews about his beliefs and was naive enough to feel sorry for Bill Clinton the predator. Osteen doesn't even seem to rise to THAT level of discernment.
At the end of each service, Osteen admonishes people who might know him only through their TV sets to find themselves a "Bible-believing church."
That would be one that completely REJECTS the nonsense of Osteen.
Is that really what it's all about?
Billy is an inclusivist- but in spite of his upbringing and education.
Osteen is a biblically illiterate self-help motivational speaker with a big smile. To call him anything theological would be to completely mischaracterize his “ministry” (unless the word is apostate, but I’m not sure you can even call him that since I’m not sure he ever ‘got it’ to begin with)
