Life throws us “curve balls”—from devastating personal losses to world tragedies. These events often leave us doubting God, the Bible, and our faith. But instead of pushing away our reservations, we should embrace them, Peter Enns argues. A leading biblical scholar and Christian mentor, Enns has never been afraid to question the Bible or Christian beliefs. Such thoughtful inquisitiveness, he argues, is part of God’s plan. He wants us to question, because doing so actually leads to a stronger, lasting faith.

By reframing how we see these events, we allow ourselves to see how the Bible itself showcases this very process and that “treating curve balls as the enemy” is not only counterproductive but thwarts God’s goal of helping us become mature and wise. Enns shares a number of curve balls he’s encountered in his own life and the questions he has pondered. Does God care about the millions of people who never heard the gospel? Could I relate to a God who has created a universe this big? If God is so relatable, constant, and caring, how do we explain quantum physics? He reveals how particular biblical passages have helped him find wisdom, and how they can do the same for us.

As Curveball persuasively shows, God is bigger and more mysterious than anyone’s expectations. We need a faith that can grow just as deeply.
