Why me?

I am puzzled by why I react differently to some others when looking at the existence of God. Why did I look at the futility of using just reason to work out if there is a God and find in that discovery the freedom to choose faith? Why do others get to a similar point and reject God? The following is a response from someone on the ex-christian.net website in response to reading my blog.

"I am definitely on the way back to finding some kind of faith again. The relief is huge! Following on from my last post, I finally realised the futility of trying to work out with just reason if there was a God." ( The Patchwork Blog from Monday 17th January 2011)

This person wrote the following in response to my blog on the ex-christian website. "Abandon reason and believe the unreasonable!   Obviously, some people aren't happy unless they have a belief in magic even if they know it is an unreasonable position as this one does. It seems that many people want so badly to think there is a god they will take the leap of faith that tells us fairies don't exist until we believe in them.   I see it all the time, but I still don't understand embracing unfounded beliefs while recognizing it goes against reason"

Getting to the same place as I did led this person to choose to reject God. It gave me the freedom to choose to have faith as an act of my will. What is it in me that makes that choice and in another person makes them reject God? Is it personality? Environment? Their past experiences of Church? Does it just boil down to the fact that I want to believe in God and so am happy to make that leap of faith? Maybe the other person did not want to believe in God and getting to that point gave them the freedom to not to believe.I don't suppose I will ever know the answer this side of heaven but it puzzles me and also makes me eternally grateful that I have chosen faith in God.
