"In her wonderful book, Questioning Your Doubts, Christina Powell effectively builds a bridge between rationality on the one hand, and faith on the other. As both a cancer researcher and an ordained minister, Christina cleverly draws analogies between her experiences as a Harvard graduate student and the harder issues that we all face navigating the Christian life. Although her analysis of the interface between faith and science is worth the read in and of itself, this book is really a comprehensive, whole-life discipleship guide for any serious follower of Christ."

"Christina Powell's Questioning Your Doubts is a unique and compelling examination of the relationship between doubt and faith. This is the rare book that is rich in content while being thoroughly enjoyable to read. It is a meaningful work deserving of widespread readership."

"Dorothy Sayers once wrote, 'Nobody could possibly guess from the words and deeds of Jesus that there was anything "funny" about woman's nature.' Christina Powell proves this, and she also proves that there is nothing odd about the brilliant relationships of science and Christendom, women in science, and women and the church. I encourage the reader to join her adventures into the world of graduate student, professional scientist, daughter, wife, mother and Christian pastor."

"Doubt can be an enemy of faith. But as Christina Powell shows in her new book, doubt can also be an ally of faith. Not only can it help you ask questions that lead to new spiritual insights, but it can also help you turn the tables on skeptics. Questioning Your Doubts is a good book, and questioning your doubts is a helpful way to grow your faith."
