Here’s a book that every coach and sports parent should have. A Guide to Biblical Manhoodby Randy Stinson.
The whole book is a great resource, but I want to point you to one chapter in particular, titled Take Me Out to the Ballgame: Baseball, Biblical Masculinity and Godly Character. It is worth reading the whole thing for this chapter alone. Randy does an awesome job of laying out how specific aspects of the game of baseball can prompt dads and coaches to live under authority, bounce back after failure, live with resilience and many other life lessons for men.
Baseball may not be your game, but this book will challenge you to think deeply and creatively about how to leverage specific aspects of your game to teach lessons in Biblical masculinity and godly character.
