This sermon emphasizes the importance of joining God's family as part of spiritual growth and the church's mission. Drawing from Acts 2:36-47, the message explores how us as believers move from encountering Jesus and experiencing healing to actively participating in the church community. Pastor Andrew stresses that effective ministry requires the Holy Spirit's power, not human effort alone. He addresses believer's baptism as a public declaration and spiritual warfare, the necessity of church membership for accountability and fellowship, the importance of small groups for deeper relationships, and the role of giving in supporting God's mission. Pastor Andrew's sermon challenges the "Lone Ranger Christianity" mentality, emphasizing that believers need intergenerational community and mutual support to grow in faith and fulfill the Great Commission.
