For Dehlin's survey of disbelieving Mormons -- and which Lds beliefs are causing them to either seriously reconsider Mormonism or to leave the church...see posts (& links) @ #1 & #2 @:
Survey on Mormon Disbelievers to be Released at UVU Forum [74% point to theological concerns]
In 2007, we suffered the worst flood in four generations. My office had two feet of water in it, and during the cleanup, we ran out of supplies. The hardware stores were closed, so we went to see if the town had accumulated any supplies. When I got to the city garage, I saw pallets of cleaning supplies and bottled water, shipped to us by the Church of Jesus Christ of Latter Day Saints.
You believe what you want to believe about the Mormans; for my part, I will never forget how they acted as Christ taught in helping a stranger in need.
