This video makes me think about how we use cognitive decision making in religious endeavors (I mean: making the mental decision the most important part of our faith).
The reality is that we are rarely faced with momentous decisions like the variety that this video suggests.
The 'snap' theory (the idea that people just one day snap and do terrible horrible things) is not supported at all in any field of study.
People make big - life changing - decisions all the time but they are rarely if ever made 'right-out-of-the-blue'. Whether it's deciding to get married, buy a car, change jobs, or lose weight - all these decisions are made with a truck load of background support. It's the same way with sin. We are never faced with these monumental temptations that overwhelm us into commiting these horrible things.
What is interesting is how we pressure (maybe this is especially in the past) people into deciding to follow Christ (accept the plan of salvation). If we realize that a momentous decision requires so much support in order to make. How can we actually think that a one time response at an alter call or other similar occasion is really meaningful in the grand scheme of things?
I think that changes how we approach these 'talks' or sermons. I think we need to remember to challenge people to consider the opportunity to make a decision but be careful not to make it so trite that we think an entire life can be magically reversed with one simple prayer or raising of a hand...
