Another introductory Christianity book, this time structured to give a Biblical history of the world: creation, the Fall, the history of Israel (mentioned more in passing), the coming of Jesus, crucifixion, resurrection, the last days and the second coming. Along the way Roberts describes the basics of Christianity.
I bought this at the same time as Rico Tice and Barry Cooper's Christianity Explored, so comparisons between the two are inevitable. Christianity Explored is more focused on simply describing Christianity, without presenting it in the more interesting way Roberts does. However, Roberts doesn't go into quite as much detail on some points (there isn't a chapter titled "what is grace?", for instance).
Overall, I think I preferred Christianity Explored, although this book is by no means bad. Aimed more for the new Christian or someone unfamiliar with it, it's probably too basic for me (without wanting to sound arrogant), so it was at times quite a tiring read for me. Like Christianity Explored, the relationship between us and God is described as "intimate", something which I'm not convinced of. He also skirted around the preterist/futurist debate, focusing solely on the second coming (nothing on the apocalypse/fall of Jerusalem). There was some apologetics in there (defending the historicity of the resurrection, the reliability of the New Testament and properly defining "faith"). However, as with most books of this type, I was disappointed that there wasn't as much emphasis on apologetics as I feel there should be.
In short, if you're after something meaty, this isn't the book for you. But if you're after something which isn't meaty, then it is for you!
A running theme through these introductory Christianity books is the use of anecdotes. Most have a few, but Roberts really goes to town with them. After the first couple of chapters, it gets tiring and awkward; you wonder if he's just trying to make the book longer (my edition is 170 pages long).
This book is also quite dated. Roberts spends quite a lot of time talking about "the new millennium" (this book was first published in 1999) and referring to contemporary news stories. It doesn't significantly affect the quality of the book, but it does jump out at you.
So in summary, this is a good book for someone interested in the basics of Christianity. It's not the best - I preferred Christianity Explored, and there's no real justification to own both books. If you've tried reading Christianity Explored or a similar book and have been left disappointed, but are willing to give it a second shot, this book may just be what you're looking for.
