My son and I have started reading together the book Just do something: a liberating approach to finding God's will by Kevin DeYoung.
There is an nice review by Tim Challies on his blog. He succinctly summaries the main points.
In some ways the book may be particularly helpful for the children of parents who need to read Ross Campbell's How to help your twentysomething get a life and get it now.
The book also reflects the social and personal problems which result from the affluence and aspiring upper middle class [that means probably means you!] of much of the church in the Western world.
The paragraph below gives the gist and tone of the book:
“So go marry someone, provided you’re equally yoked and you actually like being with each other. Go get a job, provided it’s not wicked. Go live somewhere in something with somebody or nobody. But put aside the passivity and the quest for complete fulfillment and the perfectionism and the preoccupation with the future, and for God’s sake start making some decisions in your life. Don’t wait for the liver-shiver. If you are seeking first the kingdom of God and His righteousness, you will be in God’s will, so just go out and do something.”
