  • Some sociologists have called our culture the argument culture. We focus on our differences and freely shoot verbal bombs at each other. I can’t believe that any of us are happy with the divisiveness we have created. Is there a road back to civility? I believe there is, and Shaunti Feldhahn is pointing the way with "The Kindness Challenge." I highly recommend this book and believe it has the potential of changing the emotional climate in our culture.

  • In her latest book, Shaunti Feldhahn has touched on one of the most important elements of any healthy relationship—kindness! We all know we should be kind, but do we know why? And how? Shaunti has provided an inspiring roadmap for anyone who wants to nurture their most important relationships.

  • This book is an amazingly powerful tool that will transform your heart and your relationships from the inside out.

    Lysa TerKeurst, New York Times bestselling author and president of Proverbs 31 Ministries
  • This concept is so simple, so profound, so doable, and so inspiring. I am taking the kindness challenge, and it is making a difference in my heart and in my home. Truly, as Shaunti’s research proves, the kinder you are, the happier you are. I am recommending this book to everyone who has any relationship issues or anyone who just flat-out wants to be a happier, wiser person.
