Exploring Theology

I am looking for suggestions for a good study of the Book of Revelation for my adult Sunday School class.   Any format (book, audio, or video) will be considered.  Please leave the name of anything you might recommend in a comment.  A brief explanation as to why you like it would also be helpful.

Thanks for your help

We say, then, that the Godhead is absolutely of itself. And hence also we hold that the Son, regarded as God, and without reference to person, is also of himself; though we also say that, regarded as Son, he is of the Father. Thus his essence is without beginning, while his person has its beginning in God.  – [from Institutes of the Christian Religion by John Calvin translated by Henry Beveridge Book 1, Ch. 13, Section 25]

Sound, biblical doctrine is a necessary aspect of true wisdom and authentic faith. The attitude that scorns doctrine while elevating feelings or blind trust cannot legitimately be called faith at all, even if it masquerades as Christianity. It is actually an irrational form of unbelief.

John MacArthur made this comment in this brief article over at Pulpit Magazine.  Doctrine does matter.  Doctrine is simply the truths that are taught in the Bible.  We are commanded to grow in our knowledge of the Lord.  That necessitates the study of doctrine.  As we study the Bible, we will learn its doctrines.  Don’t neglect your study of the Bible, it is vital to your spiritual maturation.
