It is, as they say, all about the Benjamins* (link).
That just confirms to me that Osteen is not a Christian teacher at all, no matter what he may call himself. If someone can locate a copy of Turretin's Institutes in their local Mormon bookstore, I'll eat my hat (figuratively speaking).
* For those unfamiliar with urban lingo, Benjamins = money
UPDATE: JohnMark at Beggars All Reformation is less suspicious of Osteen - and simply sees this as confirming the vacuity of Osteen's writing (link).
