Over Over and over again, the Bible calls believers to love and care for one another. That has never been easy. But now, in a time of extraordinary pluralism, the many differences among Christians make the commands to love one another seem almost impossible.

Yet Gerald Sittser believes the commands still apply, perhaps especially in light of our divisions. In several insightful chapters, he considers such "mutuality commands" as greet one another, forbear one another, comfort one another and admonish one another.

Sittser does not duck the hard issues. Yet his book is warm and hopeful. It is marked by close attention to the Bible and dozens of real-life stories that show how we can, indeed, love across our differences.
