The sermon draws from 1 Corinthians 12 to present the local church as a unified body in Christ, emphasizing that believers—regardless of ethnic, social, or economic background—are joined together through the Spirit and united under Christ as the head. Central to this message is the theological truth that every member, no matter how seemingly insignificant or uncomely, is essential to the body's function and purpose. The threefold purpose of the church—glorifying God, edifying believers, and evangelizing the lost—is grounded in the practical realities of assembling together, praying together, ministering together, and striving together in faith.
