Michael Flournoy spent three decades as an ardent follower of the Church of Jesus Christ of Latter-day Saints, which is more commonly referred to as Mormonism. He served a mission in Anaheim California where he publicly debated Evangelical Christians. After returning home he published a book called, "A Biblical Defense of Mormonism" and continued to debate Christians online and in public. In 2015, he decided to study grace in an attempt to become a more effective weapon, and the truth he discovered shook his beliefs to the core.
