The action is quite similar to how marketing groups incorporate the word or idea of "Magic" into a product association, it invokes the imagination and just like sex, it sells! If they could get away with having Jesus or Moses pitching the product, they would use it simply because the idea that something is "special" due to its association... if you buy this cream you'll look like this model... drive this truck and you'll be as cool as this actor or sports figure... use this software and you'll possess psychic-like ability/advantage, etc.
HOPE and the fantasy thereof, is the biggest sales trick going... look at the Obama presidential campaign
