If you’ve read the interview with Garry Williams then you’ll know that the atonement is a subject he has/is devoting his life and studies to. You’ll also know that Jonathan Edwards is the person he’d most like to meet from church history. Back in 2006 I had the opportunity to hear Garry at the Banner of Truth Minister’s conference in Leicester where he gave two addresses on Jonathan Edwards and the atonement. They aren’t the easiest to get your hands on, but are worth the effort (contact Rev Ian Densham, 19a Alexandra Road, Hemel Hempstead, Herts, HP2 5BS for these CDs). I remember being struck by the enormity of my sin, and then the enormity of Christ’s love. The precision of Edwards is helpful on this topic. I also remember closing the second session singing “O the deep, deep love of Jesus.” I don’t know your view of psalms/hymns, but that was the perfect hymn to close with.
One thing to add on the value of Garry’s two sessions. They are historical and theological, but with a very practical bent to them. He is pastoring pastors in these messages (as his others from the Banner conference this year). It is not merely head knowledge, but it has a very sharp point of application. These particular messages on Edwards will require your full and focused attention, but surely the gospel and the work of Christ deserve that.
