"Just do something": the title sums up the book well. The author takes careful aim at those whose think following God's will means doing nothing without some specific piece of heavenly guidance, and who thereby end up in a kind of super-spiritual paralysis.
But DeYoung's interest is not merely in point-scoring; he has a pastor's concern to help those hamstrung by fear of having 'missed God's will'. He emphasises that if we are living for God then God has undertaken to guide us at the points where it really matters. He emphasises a right freedom, and, crucially, a reponsibility, for Christians to live, grow and build within the bounds set by God's biblical revelation of his will.
DeYoung avoids falling to the 'other extreme' of teaching that God's guidance is purely limited to his revelation in scripture. He is thorough and pretty balanced, though brief, in looking at supernatural spiritual gifts, and at guidance in the lives of the Apostles. My criticism would be that he is just a tad too dismissive of the expectation of the Holy Spirit's direct leading into the 'good works prepared for us to do'.
With some inspiring stories about his grandfather, a simple Godly activist from the days where you had to get up and do something if you were going to keep eating, DeYoung challenges what he describes as the mere 'tinkering' of his own generation.
There is a great chapter on dating and marriage in which he encourages people to 'get on with it' (where appropriate!), and specifically reminds Christian men to be men: to take a lead and take responsibility in relationships. And it's good that he warns people never to think of divorce as an option if they've married 'the wrong one'. He does assume in passing that it would be OK to marry the innocent party from an earlier divorce; and perhaps it would have been good just to mention that not all evangelicals would hold that view.
I read through this book in little over an hour, but it will also repay closer study. Great for a 'refresher', or as a book to give new Christians or those facing decision time.
