One of Osteen’s many available sermons online is titled “The Power of ‘I Am'” (also on YouTube). Reportedly, this is the sermon that Winfrey says changed the way she saw her life. It is also a very popular video of Osteen’s that millions of others have seen. Perhaps due to criticism of the speech for its interpretation of Christian values and principles (per Challies), it makes one curious as to what the legendary talk-show host heard that was life-changing and why the sermon has become so popular.

Winfrey and Osteen had previously spoken of the keys to maintaining one’s power, so it’s no wonder his preaching struck a chord with her. In his sermon, he talks about everything from self-worth and the outside forces that make us feel insecure to how we react and internalize it and how negative thinking can impact how one can view oneself. He also said that having an attitude such as foreseeing weight gain or something like clumsiness, will only attract it.

Winfrey never specified what area of Osteen’s 30-minute long teaching connected with her the most, but in the past she has publicly battled self-image issues mostly surrounding her drastic changes in weight. It’s an issue she’s openly discussed on her show many times since the late ’80s (via Oprah), and continues to talk about (via People magazine). But seeing as how he’s changed her life, presumably in a positive way, Winfrey no doubt feels a personal connection to the Texas-based pastor that she likely holds dear — despite the many who may not understand it.
