They are stupid only if you want them to be.
Can we marvel, along with St. Paul, that “whether or not for profit, the gospel is preached.” You really have to beg the question to play the grinch here. I have personally seen scripture mean things to me that the person who quoted it may have never caught on to. The name of the game is to praise the Lord not to traduce the Osteens. Nobody is asking you to be an Osteen. They will get their reward or lack thereof in the fullness of time.
The gospel has never been preached by Osteen.
He says there are multiple ways to Yehova.
The gospel says that Yeshua is the only way.

Even pastors must eat, thus must make money from preaching.
