Is it possible to have too much of a good thing? One way the adversary tries to derail our eternal progress is by perverting virtues into vices. Pressing forward is clearly a virtue, but running faster than we have strength doesn't get us to heaven faster--it just burns us out. So, Satan succeeds whether he persuades us to saunter aimlessly or to sprint the marathon of life at a frantic and unsustainable pace. Seeing the dangers of each extreme illustrated by powerful, practical insights, we can identify our own spiritual weaknesses and learn how to find a healthy balance in life.
