It takes a little time to get to the aspects of diversity, but is rewarding once he ties it all together. His emphasis on interpersonal interaction (ie joint fellowship, sharing meals) is so key. As I have written before, ‘Hit and run’ diversity encounters just don’t cut it–not even close.
The image of the body of the church (Eph. 1:19-23) is often used in the context of church diversity, but Walls does a particually solid job of emphasising our culture-specific perspectives on God as necessary to our complete understanding of the Father, and our requiring one another in this way for the sake of our salvation.
