Charles D. Drew writes about Calling in A Journey Worth Taking. This book is worth the money and the time. I've read it twice now and it is a top-notch book on the topic of purpose and meaning in life.
This book puts a frame around what it means to live to the glory of God - that is our calling. Calling? What is it? What does it look like? It is much more than having the right job for your personality type and living a purpose driven life. All Christians are called simultaneously on three levels:
1) To deep relationship with God - knowing him better.
2) To faithful and joyful self-discovery.
3) To service - work that simply needs to be done in an imperfect world.
What I really like about this book is that Drew works out the implications of the biblical road map of four big ideas:
1) Creation - we were built with a purpose
2) Fall - because of sin we display that purpose in terribly wrong ways
3) Redemption in Christ - all things are made new and can be done to the glory of God
4) Consummation - what we do on earth matters because everything points to eternity.
This book is not a trite formula for a better life now. It is not a cute self-help gospel present wrapped with out of context scripture passages. This book is a display of heavy theological concepts welded together with everyday questions and answers about how Christians should live life and what to expect.
