Here is a call to holistic Christianity. A challenge to be thinkers, engaged and serious about knowing God. And to be feelers, pulsing with passion for Jesus and his gospel. And to be doers, endeavoring great acts of love for others.John Piper & David Mathis
I love this book. It was very helpful to me both intellectually and spiritually. Written by a number of authors including Francis Chan and R. C. Sproul, this book is one which hits the heart.
