A friend of mine, Doug Searle, who is the Director of Administration at Community Bible Church in Nashville, is teaching a study through the book of Hebrews called Privilege & Perseverance-A Study of the Book of Hebrews. That link to his blog has all the handouts used in the class as well as the MP3's of the lessons. Let me encourage you to take advantage of this excellent series of verse by verse studies in the book of Hebrews taught by someone who really loves the Lord and is a great encouragement to me.
Lesson 1 is in two parts. (Part 1) (Part 2)
After all, who can get too much verse by verse bible exposition, huh?
