The Truth is hard for people to Know

Maybe I should make that stronger - the Truth is very hard for most people to arrive at. There is something about it that makes it hard to grasp, which makes it hard to understand. 

I will use the Religion of my family as an example: Mormonism, and the Book of Mormon specifically. 

Joseph Smith wrote it himself and millions now believe in it, or anything affiliated with it. 

I have to ask: what is going on here? You can say "This typical of Religion and cannot be explained. And is typical of many other things, that cannot be explained." 

There are at least two kinds of things: Scientific and Nonscientific. And the Noncientific are now more popular.
