For La Parisienne and Dr. Doolittle, as we have long been saying exactly this. Oh, sure, I'm a mean, nasty person for calling out such an inoffensive, smiling nice guy as Joel Osteen, right? Whatever. He and his Prosperity Gospel bandwagon are factually wrong in terms of orthodox doctrine, and no number of toothy grins and amazing hairdos is going to turn his pulpit-based motivational speaking into the actual gospel.
It's marketing genius that tells a bunch of people exactly what they want to hear, but its popularity doesn't mean that it's not a pile of unbiblical hooey. You don't have to be a Christian to see that. You don't have to adhere to any religion at all. You only have to be a person with neurons and a basic ability to compare one set of statements with another and see that the two don't match.
On a related note: It doesn't matter if Osteen's shallow, happy-slappy, brain-dead, self-centered, "God is my cheerleader" pablum makes you feel good. "Feeling good about yourself" and "getting stuff" and refusing to talk honestly about sin and human failing are not the point of Christianity. There, I said it.
