The church exists because Jesus is alive and continues His work through His people by the power of the Holy Spirit. Acts shows that the church didn’t start with programs or preferences but with a community gathered around Jesus, waiting for the Spirit, and then sent out as witnesses. The Spirit empowers believers not for comfort but for mission—beginning at home and moving outward to the ends of the earth. The church is not something we consume; it is something we are, and its purpose is to testify to Jesus.
