This interview was recorded live on-site at the 2016 IBCD Summer Institute entitled Disordered Desires: Bringing Grace to Modern Sexuality. Our guests were Iain and Barbara Duguid. Iain is a professor at Westminster Theological Seminary, a pastor at Christ Presbyterian Church in Glenside PA, and an author of numerous books and commentaries including The Song of Songs: An Introduction and Commentary. His wife, Barb, is the author of Extravagant Grace: God's Glory Displayed in Our Weakness, and Prone to Wander: Prayers of Confession and Celebration. In this episode our host, Craig Marshall, talks with them about how they came to be speaking at a biblical counseling conference and their passion to help believers grow in their understanding of the gospel. They discuss together their desire to help Christians understand their present struggles with sin in light of God's sovereignty and grace.
