Nicky Gumbel choses 7 topics based on the frequency with which they have been raised as 'What about' questions by people he has met on Alpha courses (astonishingly successful courses that introduce key ideas about the Christian Faith). The chapters are 'Suffering', 'Other Religions,' 'Sex Before Marriage,' 'The New Age,' 'Homosexuality,' 'Science and Christianity' and 'The Trinity.'
The approach of using summaries, anecdotes and practical advice is engaging, very readable, persuasive, concise and extremely useful in the presentation of Christian answers. This book has depth, but does not set out to provide a thorough academic treatment of each topic - instead directing the reader to further reading if necessary.
This book never sets out prove God's existence. A feature it has in common with the Bible.
I recommend it to anyone who would like a clear Christian explanation of these often problematic areas. I enjoyed reading it very much and hope to make use of what I have learnt from it soon.
