I reluctantly went through a group study with this book. There is hardly any good instruction here. It seems that it is supposed to stimulate conversation, but the questions it poses hardly ever do because they are so simple. I've studied the Bible fervently for the last 35 years so it's not like I'm pulling this out of a hat. I don't know what the others are like in this series, but if this is any indication be careful. I've had a much more fruitful experience with the Navigators series because they are more in depth, which stimulates more discussion.
