Book excerpt: WHEN YOU COME TOGETHER brings us back to primitive theological truths such as the church as family, the body with its interconnected parts and the presence of the Holy Spirit, Who delights to reveal God's heart and mind to His gathered people. Amy Anderson contends that belonging to God's people should involve us all in something less like a music concert and more like a jazz session--with every person participating as an essential instrument, following a common thread while also expecting the Holy Spirit to weave new themes into the established patterns. Anderson provides a nitty-gritty guide to both why and how we can ditch the concert paradigm and instead learn to gather alertly in God's presence, allowing Him to speak in our midst and turn our lives upside-down.
