Sometimes it seems we just can't get what we want. Circumstances thwart our best-laid plans. We struggle to live a heartfelt life. Worst of all, says Eldredge, the modern church mistakenly teaches its people to kill desire (calling it sin) and replace it with duty or obligation (calling it sanctification). As a result, at best Christians tend to live safe, boring lives of resignation. At worst, their desire eventually breaks out in destructive ways such as substance abuse, affairs, and pornography addictions.
