The blurb.
In Running Scared, Edward T. Welch investigates the roots of fear in the human soul and the ramifications of living in the grips of anxiety, worry, and dread. Welch encourages readers to discover for themselves that the Bible is full of beautiful words of comfort for fearful people (and that every single person is afraid of something). Within the framework of thirty topical meditations, Welch offers sound biblical theology and moment-by-moment, thoughtful encouragement for life-saving rescue in the midst of the heart and mind battlefield of rampant panic-stricken responses.
This comprehensive primer on the topic of fear, worry, and the rest of God will have readers retreating to scripture for invariable constancy, stalwart care, and robust comfort, instead of as Welch terms it, “hitting the default switch” by responding with characteristic human independence, control, and self-protectiveness.
