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.
