My Inflatable Heart is a collection of short stories about life and the pursuit of happiness. Many but not all of the stories tell of the author's work with disabled kids as the director of Young Life Capernaum in Hampton Roads, Virginia. Through this work, Koehler learned things about himself and the people that God called him to serve, as well as the "normal" people of the world. These stories will challenge the reader to think beyond the typical boundaries of religion and spirituality. Koehler questions everything and wonders about things that are mysterious or right next to you. He attempts to cross the divide between the world we live in and the place we call Heaven. How is it possible for God to use ordinary people to do extraordinary things? Can disabled people become God's disciples? These questions and many more are grappled with by Koehler, aided by a heart that expands and contracts like a hot air balloon.
