I can't say as I agree with everything that Francis Chan, who created the video for which this book is a study guide, said. He seems to be saying that, in order to be a true disciple of Jesus, you should be prepared to give up everything - including your life. On one hand, I don't disagree with that. On the other hand... are we all meant to give up everything? Are we expected to quit our jobs, sell our homes and travel around guiding others onto the road to discipleship? That's quite a lot to ask.
There are a fair number of questions that are straightforward study guide type questions, with straightforward answers. (i.e. - Who was it that went to Jesus's tomb?) At the same time, there are a fair number of thought-provoking questions. Some of them, I don't have answers for even now - having finished reading the study guide. I'm still praying about the answers to those questions.
It's not a bad book, even if you don't agree with everything Chan thinks and I feel like I got a lot out of it. It's definitely better to work through it with a group of people, as I did. (We read this book as part of a Bible study.) I can't imagine trying to read through it alone, without any input from other people, but I suppose it could be doable.
It's worth noting: there's a video series that goes with this study, but... it as $80, so we opted to just read the book along with our Bibles. It might have added something to have watched the videos each week as well.
