Lakewood Church worship leader Israel Houghton says after working with Pastor Joel Osteen for more than 11 years he can testify that "he's the real deal." The Grammy award winning gospel singer says he knows that some Christians dismiss Osteen's preaching as little more than positive thinking. But Houghton says he's seen the changes God has worked in the lives of members of the nation's largest congregation. What kind of changes, and in how many of the 10,000+ attendees? If growth programs exist at Lakewood, they're not obvious, and (based on the classes they do advertise) they don't have any depth. Does Joel Osteen think that Christians can grow to instant maturity like Sea Monkeys?
