Book excerpt: If you are serious about being a disciple of Jesus Christ—really, truly serious—a discipleship group can help you achieve that goal. Jesus established this model for us by forming and leading the first discipleship group—and it worked. The men who emerged from that group took the gospel to the world and ultimately laid down their lives for Christ. Discipleship groups can create an atmosphere for fellowship, encouragement, and accountability—building an environment where God can work. In Growing Up: How to Be a Disciple Who Makes Disciples, Robby Gallaty presents a practical, easy-to-implement system for growing in one's faith. This guide offers a manual for making disciples, addressing the what, why, where, and how of discipleship. D-Groups, as Gallaty calls them, can teach you and others how to grow your relationship with God, how to defend your faith, and how to guide others in their relationships with God. Growing Up provides you with an interactive manual and resource for creating and working with discipleship groups, allowing you to gain positive information both for yourself and for others as you learn how to help others become better disciples for Christ.
