Whilst away the main book i read was by Donald Miller called 'Blue like Jazz' - there's a fair amount of buzz about this one around as it offers what Miller calles 'nonreligious thoughts on Christian Spirituality'.
It's a good read and approaches the issues of faith and what it means to be a Christian in a very accessible way. A collection of essays, the language is straightforward and the style quite simple, yet there is plenty to think about in this book. Some of the insights are surprising, some seem banal yet are filled with meaning. It's a book of contradictions - simplicity with depth, poignancy with humour, meaning in meaninglessness. It's certainly a good introduction to the core of Christian faith, which is Jesus Christ, and responds to many criticisms aimed at church and Christian believers with down-to-earth yet passionate conviction.
Its laid back style, which some might find infuriating, belies the passion with which Miller has sought to know Jesus. It doesn't try to answer any questions, but offers obvservations on the deeper reality of faith and meaning. Worth buying, IMHO.
