Robert Reymond has been publishing quite a few really good books for the past few years, including a Systematic Theology that many say replaces Louis Berkhof’s. He is Professor Emeritus of Systematic Theology at Knox Theological Seminary. These are a series of sermons he delivered at Second Presbyterian Church, Greenville, South Carolina.
Bethlehem Bible Church of Boylston, MA has a large, very well organized and accessible audio section. Sermons can be organized by speaker, title, date, top downloads or Scripture reference. The 4 elders and a number of deacons rotate teaching. They have also had some very interesting guest speakers including Steve Lawson, John MacArthur, James White, Robert Reymond, Don Whitney and more.
