People will fall for most anything that they think will help them in the moment. The selling of snake oil in days gone by, the current weight-loss pills, the almost daily introduction of a new pain reliever, or depression destroyer, etc.--virtually anything promising to move me away from pain and toward pleasure.
These are the two motivations upon which all persuasion is built.
Christians and pre-Christians are no less gullible.
"Prayer Changes Things."
"God Answers Knee-mail."
"Seven Days Without Prayer Makes One Weak."
