The original discipleship book written by Dr. Marcus Warner, Toward a Deeper Walk, first introduced the term "heart-focused discipleship" to readers.

The first half of the book presents three core pillars of a biblical worldview that create a model for understanding the Christian life:

• Sacred romance
• Sovereign lordship
• Spiritual warfare.

The second half of the book unpacks what it means to walk in the Spirit. It introduces the S.L.O.W. acrostic (Seek, Listen, Obey, Watch) and offers a chapter on each of these practices.

The book is very practical and a great introduction to a journey of the heart.
