In this message, Pastor William McDowell asks, “Why do I need the church?” and answers that it’s the only place on earth where the Holy Spirit invites us into the eternal fellowship (koinonia) of the Trinity. He exposes the loneliness of our culture and the limits of “spiritual but not religious,” showing that the church is a time-traveling family that makes the future kingdom visible now. This sermon challenges Western individualism and calls believers to live out Jesus’ command in John 13:34–35through sacrificial love in real community.
