ADRIAN PLASS and Jeff Lucas are writers and speakers individually well-known and well-regarded in Evangelical circles. Each has a reputation for being funny and honest about the reality of day-to-day Christian life. Together, they have toured the UK with Seriously Funny, an evening of improvised conversation, followed by a Q & A session with the audience.

All Questions Great and Small: A seriously funny book (Hodder & Stoughton, £8.99 (£8.10); 978-1-444-79316-1) takes some of the questions that they have been asked, to which Plass and Lucas provide individual replies. Some of the questions are serious, such as: “Will only Christians go to heaven?” and “Can I be a Christian if I still have doubts about God existing?” Others are deliberately daft, such as: “Jeff, do you wear eyeliner when preaching?” and “Are you frightened by any fruits?”

Many of the questions took me back to my Brethren upbringing in the 1950s and ’60s. I wonder, are Christians still worried about drinking alcohol and enjoying magic? Plass is a self-deprecating sage of the Evangelical soft-left, and his evident dry humour works best when he is not trying to be funny. Lucas mostly tries too hard, and tends to sound flip, though his account of waltzing with his mother when she was lost in dementia is touching, and real.

To get the most out of this book you would need actually to care about what the authors thought; so this will appeal to the already converted.
