Most people who believe also doubt sometimes. Some experience doubt as a sign that something is wrong with them. The Bible shows something else: the doubt is there, and it is allowed to come along.
Doubters in the Bible
Thomas wanted a sign before he believed that Jesus had risen (John 20:24–29). The psalmist cries out to God about why he is so far away (Psalm 13 and Psalm 88). The father in Mark 9:24 says: “I believe; help my unbelief.” All are taken seriously.
Doubt is not the same as indifference
The one who doubts often cares more than the one who never asks. The questions can lead to a deeper faith, or to more questions. Both are allowed.
What can you do?
Read honestly, and write down your questions. Talk to someone you trust, preferably someone who can stand questions. Use Ask the Bible to see what different traditions say, and read the verses yourself.
If the doubt feels heavy and dark, and is not just a question, it is wise to talk to someone: a friend, your priest or your doctor. That is no weakness.
