Everything by Mary DeMuth is a good, challenging book! It is broken up into 3 sections. Part 1 is Head - What We Think. Part 2 is Heart - Who We Are and Part 3 is Hands - How We Live. Basically, these three components add up to 'everything'. Jesus wants our everything - Head, Heart and Hands.
At the end of every chapter are Questions for Reflection and Discussion, that really add to the book. These questions would also be useful if you were to do this in a group study. Mary writes from the heart and is very sincere and passionate, as well as very open about her life and journey. Because of this, it doesn't sound like a sermon, but one person earnestly sharing her journey with others.
Everything is a good, challenging book. I enjoyed it more than I thought I would.
