People act like questioning one’s faith is a bad thing.
We should first understand the two meanings of the word faith. Faith in the Biblical and Book of Mormon sense is a verb. Faith, as the Lectures of Faith tells us, is us the first principle of action. The other definition of faith is a noun. This definition of faith is a set of beliefs that one must adhere to in order to be considered a member of a group.
The two meanings should never be confused. The two meanings work against each other. Faith as a verb is active, dynamic, ever-expanding, ever-evolving. We express belief by planting a seed. Belief becomes faith. Faith becomes knowledge. Then, we plant another seed, and the cycle continues. (Alma 30) Faith as a noun, i.e. a system of belief, is just what it says it is: a system designed and engineered to make sure you remain in a belief.
The answer to a faith (noun), is to exercise faith (verb).
Faith (as a noun) SHOULD always be questioned. PROVE (faith as a verb) everything and and hold fast to that which is good. And the corollary to this is, if it is not good, get rid of it.
The problem, as I see it, is people have NOT been questioning their faith, but simply taking everything on faith. There is a subtle difference. But, one day reality, as it is always prone to do, creeps up on them and forces them to make a decision. This is known as a crisis. In this case it is a crisis of faith. People suddenly realize that their faith (noun) is not serving them.
