Ken Costa is a banker and chairman of Alpha International. The business world is the background for this book. His claim is that the underlying issues discussed are the same for all Christians, whatever their background. I agree. The messages are relevant for all engaged in the difficult challenge of living out their Christian faith at work, including those in medical practice. God at work addresses the problems that confront us all – stress, disappointment, failure and making difficult decisions. There is advice on maintaining a good work-life balance and achieving spiritual renewal. Another area Ken highlights is the concept of joy in work. I found one quote quite unforgettable: 'My work station is my worship station'. He points out that an eternal perspective on life can put the stresses and strains of a career in context. In medicine, the problems of the reconfiguration of NHS services and the MTAS fiasco are but two examples where application of this perspective would be beneficial. Christians are not taken out of the world but Jesus did pray that we may be protected from the Evil One who loves to confuse and discourage. I found this book stimulating, thought provoking and encouraging. I recommend it.
