Osteen and Oprah Teach False Doctrine RE: I AM

Chris Rosebrough of Fighting for the Faith (www.fightingfor...) discusses a recent episode of Oprah's Life Class, Joel Osteen discussed the topic of I AM. Unfortunately for everyone tuning in they were not introduced to the I AM of the Holy Bible. Instead, they were taught to declare I AM affirmations over their lives and their futures as if their words possessed magical properties that could change their destinies. Did they teach truth or false doctrine and who is the I AM of scripture?
