A story from NT Wright:
A friend of mine described the reaction when he went home, as a young teenager, and announced to his mother that he'd become a Christian.Alarmed, she thought he'd joined some kind of cult.'They've brainwashed you!' she said.He was ready with the right answer.'If you'd have seen what was in my brain,' he replied, 'you'd have realized it needed washing!'Of course, he hadn't been brainwashed. In fact, again and again - and this was certainly the case with my friend - when people bring their lives , their outer lives and inner lives, into the light of Jesus the Messiah, things begin to become clear.If anything, it is the surrounding culture that brainwashes us, persuading us in a thousand subtle ways that this present world is the only one there is. This is seldom argued. Rather, a mood is created in which it is easier to go with the flow. That's what happens in brainwashing. What the gospel does is to administer a sharp jolt, to shine a bright light, to kick-start the brain, and the moral sensibility, into working properly for the first time.
