I recently taught an expository study on the book of Romans on Sunday mornings. I used several sources including but not limited to the works by: David Bernard; F.F. Bruce; Adam Clark; Robertson's Word Pictures; Lange, Schaff & Woods; The Expositor's Bible Commentary and Kelsey Griffin. If you find anything useful in this study it probably came from one of those sources. If you find any errors, they certainly came from me.
