At times, when we recite something regularly, it can become rote. (That's on me, I know. But such is human nature.) Similar to books I've read that helped me better appreciate the Lord's Prayer, the Ten Commandments, Psalm 23, etc., this study deepened my understanding of the Apostle's Creed--especially the biblical foundation of every statement in the confession.
I also enjoyed the author sharing about her experiences as a Christian in a non-Christian-majority country. As American Christians, it can be easy to take for granted that we can confess and express our faith freely.
I did this study with a fellow pastor's wife. It leant itself well to a one-on-one format, but I think it could work within a group setting too.
It always feels kind of strange to rate a Bible study, but not all Bible studies are created equal.
The reason I didn't give this book a higher rating is that sometimes the questions could have been more effective, and the organization and physical layout left something to be desired. (As a former instructional designer and current publishing professional, I admit that my standards for such are likely different than the average reader.)
Overall, I'd recommend this study for anyone who's interested in learning more about the content of the Apostle's Creed.
