In the past when I’ve taught doctrine courses in our adult Sunday School, I’ve simply adapted the material I wrote for my high school students. At this point, however, I’ve decided to write up eight series of doctrine lessons for adults that go into greater depth than is to be found in The Bible Tells Me So. The first of these is a series on the Doctrine of Scripture, which is now available on the website. I have drawn from earlier work I have done on this subject, including Defending Your Sword, but have also added research from other sources. By the way, this is the fortieth adult series available for purchase on the website.
