Southern Baptist Theological Seminary’s resources section has an interview between Josh Hayes (JH) and Heath Lambert (Hl), co-editor of the book: Counseling the Hard Cases. I haven’t read the book but I’d like to.
JH: Why is one’s understanding of the doctrine of the sufficiency of Scripture important for how a person approaches counseling?
Hl: Denying the sufficiency of Scripture is one of the most unhelpful things you can do in ministry. The extent to which we limit the Scriptures in counseling is directly related to the extent to which we limit the help available to those who come for help. Whenever you do counseling you need to understand what is wrong with people, and you need to be able to chart a path forward concerning how to fix what is wrong. Scripture is the only book that reveals God’s authoritative, powerful and sufficient understanding of each of these things.
