This book i was recommended to read after attending a church service and kind of thinking is God at work with me when i am there? What does he feel about my investment banking job as it isnt really helping anyone and not something that he would choose for me if i was really following Him. But i was so wrong. This book tells you exactly all those answers that you are looking for. It is a practical and helpful guide to living in the world but not being of the world. Read it, it will change your work life for ever.
