I was blessed to grow up in St George’s Tron Church in Glasgow under the teaching ministry of people like Eric Alexander, Sinclair Ferguson, David Ellis, Richard Buckley and others. Some time ago I found the great Tapes from Scotland website which has literally thousands of expository sermons and talks by them and other great (mainly Scottish, all male, broadly Reformed) preachers such as James and George Philip and William Still.
I’ve adapted their spreadsheet of the recordings so as to include links to each recording on their site and you can access and sort through them here.
