As a practicing Christian and member of the church of Jesus Christ I was taught, and teach regularly, to question everything. Questions are how we build understanding and faith. The last chapter of the Book of Mormon is an admonishment to reflect on what is written, to think about, ask questions and to pray about it.

What I think too many very intelligent people forget is that faith and knowledge are two different things. But, if you want to start a project, a business, or a relationship... You need both. One feeds the other.
I choose never to undermine the faith of others because it is those strong beliefs and acts of faith that created light bulbs, assembly lines, search engines, massive online book stores and put us in the moon again and again. Faith is pretty powerful stuff
