 Along those lines, we hope you've taken advantage of the new spiral-bound Bible studies that we've created for Revelation. I'm referring to the Searching the Scriptures Bible studies that provide interactive notes for every one of Chuck's sermons. There are three workbooks in the study of Revelation. It's called Unveiling the End. You can purchase the Searching the Scriptures workbooks right now by calling us at 800-325-7000.
