Hilariously apt approach to "spreading the gospel".  The entire practice of "evangelizing" is no more than using manipulative techniques to convince a person of something that is clearly and obviously false.

IE "a guy rose from the dead 2000 years ago and that matters to you" is very hard to swallow for any thinking person, so you need to rephrase, use trickery, and manipulative techniques to sell the concept as "truth".

Fully aware of this, Campus Crusade for Christ, a leading "evangelizing how to" organization actually put together a "card trick" promotional video to help you use manipulation to  win converts.  I don't know if they are aware of the irony or not...

Either way, its interesting to see their true colors revealed in this way.
