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.
