Oprah Winfrey’s “Next Chapter,” a weekly series that premiered Jan. 1, will feature America’s most “influential spiritual leader,” Joel Osteen, in a tell-all interview discussing faith, marriage, power, and ego. The episode will air Sunday, Jan. 8 at 9 p.m. ET on Winfrey’s cable TV channel OWN. The teaser for “Oprah’s Next Chapter” shows the talk show queen asking Osteen hard-hitting questions, including those about “keeping his ego in check” and the “money” that allows the megachurch leader to live the lifestyle he currently has. Osteen, senior pastor of Lakewood Church in Houston, Texas, gives viewers behind-the-scene access to his life, his wife Victoria, and his critics.
