From the article:
In our Sticky Faith research, geared to help young people develop a Christian faith that lasts, a common narrative emerged: When young people asked tough questions about God at church, often during elementary or middle school, they were told by well-meaning church leaders and teachers, “We don’t ask those sorts of questions about God here.” While they rarely storm out of the church like Jobs did, they end up believing that the church is not big enough to handle their tough questions, and thus neither is God.
According to our research at FYI, this suppression of doubt can sabotage a young person’s faith. Contrary to what many of us might believe, students who feel the most free to express doubt and discuss their personal problems actually exhibit more internal and external faith indicators in high school and college. Doubt in and of itself isn’t toxic. It’s unexpressed doubt that becomes toxic.
