Book excerpt: This book provides a comprehensive biblical and theological survey of the people of God in the Old and New Testaments, offering insights for today's transformed and ethnically diverse church. Jarvis Williams explains that God's people have always been intended to be a diverse community. From Genesis to Revelation, God has intended to restore humanity's vertical relationship with God, humanity's horizontal relationship with one another, and the entire creation through Jesus. Through Jesus, both Jew and gentile are reconciled to God and together make up a transformed people. Williams then applies his biblical and theological analysis to selected aspects of the current conversation about race, racism, and ethnicity, explaining what it means to be the church in today's multiethnic context. He argues that the church should demonstrate redemptive kingdom diversity, for it has been transformed into a new community that is filled with many diverse ethnic communities.
