There is great hope in God’s power to change, and everyone needs to be changed. This study explores what God does when he saves someone, answering questions such as: What is the change we need? How does conversion happen? What are the fruits of salvation? Participants will gain a biblical understanding of conversion and the implications both for themselves and for the church. A series of ten 6–7 week studies covering the nine distinctives of a healthy church as originally laid out in Nine Marks of a Healthy Church by Mark Dever.

Conveniently packaged and accessibly written, the format of this series is guided, inductive discussion of Scripture passages and is ideal for use in Sunday school, church-wide studies, or small group contexts.
