Used with one of the teens in my ministry. He wanted to learn about the book of Acts, so we went through this together. Good tool. Not extensive, but excellent as a helpful resource to anyone new to the book. Mostly focuses on assisting the reader in making observations and noticing details about the text.
I assume Stott's other books like this one are equally good. Good for one-on-one discipleship. Probably good for a Sunday School class or small group.
