We believe that in the Doctrines of Grace we find a richly Biblical theology of how it is that God saves sinners. The sermons linked below (all by John MacArthur) expound upon these great truths and it is our prayer that the Lord would use them to increase your affections for Him, and bring you to a deeper sense of awe at who God is and what He has done.

The Doctrine of Election (Part 1, Part 2, Part 3)
The Doctrine of Actual Atonement (Part 1, Part 2)
