Its brainwashing, pure and simple.
This is the heart of the evangelical, fundamentalist, born-again agenda. What's sad is the same pastor (Becky Fisher) who runs it now runs something called "Kids in Ministry".
Christianity, esp in the USA, has become a cult. No longer are they just nice people who emulate Christ and believe in peace and loving their neighbor. Now they are literist psychopaths who seek to convert and destroy. The only thing that separates them from extremist Muslims is the killing part (and even that doesn't separate them considering the early history of the religion...).
(Person below me gave a smart answer, one reason I respect Orthodox and Catholic Christians. They don't sell religion like Protestants/Evangelicals do).
