Among the issues addressed by Pres. Uchtdorf is that of having questions about the Church and its doctrine (and I think it doesn’t do violence to his intentions to add “and its history”).
Now, the next issue. What about doubts and questions in principle? How do you find out that the gospel is true? Is it all right to have questions about the Church or its doctrine?
My dear young friends, we are a question-asking people. We have always been, because we know that inquiry leads to truth. That is how the Church got its start, from a young man who had questions. In fact, I’m not sure how one can discover truth without asking questions. In the scriptures you will rarely discover a revelation that didn’t come in response to a question.
