I was raised as Catholic and started seriously questioning my faith when I was a teen. My Sunday school teachers dismissed my doubts with a slightly annoyed "well, you just have to have faith."
My mom then arranged for me to have a chat with an elderly priest she knew, a very down-to-earth, nice old fellow. "Difficult question: I don't know the answer to that, but here is how I try to deal with it" was actually his answer to many of my questions. He talked at length about how having faith doesn't mean never experiencing doubt, how being in nature always made him feel closer to God, and about how things in the Bible are often allegorical and don't have to be taken literally. I still became an atheist, but it was a nice, honest conversation nonetheless. A lot of Christians could benefit from having one.
