Some memories are permanently seared into our childhood brains with a hot iron of adrenaline and fear. For five-year-old Greg, it was the memory of his ma walking back to the house after confronting his stepdad with a splintered, bloodied baseball bat in her hand.

Greg Stier was raised in a family of bodybuilding, tobacco-chewing, fist-fighting thugs. He never knew his biological father because his mom had met his dad at a party; she got pregnant, and he left town. Though his mom almost aborted him, in a last-minute twist, Greg’s life was spared for so much more.

Unlikely Fighter is the incredible story of how God showed up in Greg’s life-and how he can show up in yours as well. This is a memoir of violence and mayhem-and how God can transform everything.
