What do the various mysteries Paul refers to make up?
The various mysteries Paul refers to make up the Body of Truth, which Paul calls the dispensation of the grace of God. Within this dispensation, or period of management, are all the Pauline doctrines that are not found anywhere else in the Bible.
Les explains that he sometimes puts this on the board as a great big wagon wheel with spokes. Within that wagon wheel are all the various mysteries that make up what he calls the Body of Truth, which Paul calls the dispensation of the grace of God. Les teaches that within this dispensation, or period of management, are all these Pauline doctrines that you will not find anywhere else in your Bible. He then begins a run through Scripture, starting back in Romans, to look at them in order.
