This book offers a measured Christian response to the diverse gender identities that are being embraced by an increasing number of adolescents. Mark Yarhouse and Julia Sadusky offer an honest, scientifically informed, compassionate, and nuanced treatment for all readers who care about or work with gender-diverse youth: pastors, church leaders, parents, family members, youth workers, and counselors. Yarhouse and Sadusky help readers distinguish between current mental health concerns, such as gender dysphoria, and the emerging gender identities that some young people turn to for a sense of identity and community. Based on the authors' significant clinical and ministry experience, this book casts a vision for practically engaging and ministering to teens navigating diverse gender-identity concerns. It also equips readers to critically engage gender theory based on a Christian view of sex and gender.
