Through the Bible with J. Vernon McGee
Dr. McGee did a five year project where he started at Genesis 1:1 and went all the way through the Bible. He's an old school preacher. When I was a new Christian, a lot of the "knowledgeable" people told me he was too simplistic, but I believe to this day that the straight teaching of the Bible is better. He passed away in 1988, but his radio broadcasts are still distributed in podcast form.
Re: sermons -
Leonard Ravenhill is good.
Also Milton Green.
Hard words, but good. I came to the Lord through Milton Green sermons.
