This session lays the foundation for understanding the Christian life and the purpose of the local church. We will explore the message of the gospel—how God saves sinners through the life, death, and resurrection of Jesus Christ—and how that gospel creates a new people called the church. Looking at passages such as Matthew 16:18–19, Acts 2:41–47, and 1 Corinthians 12, we will see that the church is not merely a place people attend but a covenant community where believers are united to Christ and to one another. This session also introduces the importance of church membership, highlighting how biblical membership involves commitment, accountability, and shared life within the body of Christ.
