If you’ve experienced times of spiritual uncertainty, you’re not alone. Among American adults who self-identify as Christian, 65 percent have doubted their faith — and 26 percent are still grappling with questions, according to a new report from Barna Group.

Only about one-third (35 percent) say they have never experienced doubt.

The responses to seasons of doubt vary. Nearly half of doubters (45 percent) walked away from church; 29 percent quit reading their Bibles, 29 percent stopped praying and 25 percent disengaged from spiritual conversations with friends and family. Nearly 4 in 10 changed nothing in response to doubt.

Many did report seeking help as they worked through their questions. Some 40 percent turned to friends or family for support, and 19 percent leaned on a spouse specifically. Nearly 3 in 10 sought answers in the Scriptures, and 22 percent relied on the church.

Only 19 percent turn to a pastor or spiritual leader for guidance in navigating their faith dilemmas.

Only 19 percent went to a pastor or spiritual leader for guidance in navigating their faith dilemmas. Other places of refuge included spiritual books (15 percent), the internet (12 percent), a counselor (5 percent), and conferences and retreats (4 percent).

In the end, 53 percent said working through tough questions made their faith stronger, while 28 percent said it had no effect. Nearly 19 percent said it damaged or destroyed their faith. Almost all evangelicals (95 percent) said confronting doubt bolstered their faith.

Church attendance seems to play a key role in helping Christians grow through doubt. Among those who identified as Christians but did not attend church, only 34 percent reported stronger faith on the other side of their faith crises.

Married adults and those with children under 18 were more likely to report improved levels of faith after times of doubt, further highlighting the importance of relationships to spiritual wellbeing.

Compared to other generations, Millennials are twice as likely to say they are currently experiencing doubt (38 percent). Millennials were also significantly more likely than others to respond to doubt by giving up on church attendance, Bible reading, prayer and Christian fellowship.

Roxanne Stone, editor in chief of Barna Group, notes in the report that Millennials already have fewer attachments to Christian institutions; they are less likely to attend church and less likely to have friends who attend.

“When they go through periods of doubt, and naturally withdraw from Christian practices and church community, they have fewer built-in Christian relationships to support them and point them back,” Stone says. “Even the peer pressure of having friends and family who are still attending church, praying or reading Scripture, just aren’t as present for Millennials. It is easier, then, for them to fully disconnect.”
