On the death of Faith -

Faith by its very nature is doomed to failure and nonexistence, as is any God that one had the original faith in. And here's why.
When one professes to have faith in a particular thing, they are questioned, and if they are completely honest with themselves and of an intelligent nature, they will question that belief themselves. There is rarely an individual that can have such strong blind conviction as to never question the sensibility of their beliefs.

Lack of faith, on the other hand, is a more stable situation. One rarely considers that they ought to believe in something when there previously was nothing there. Someone who has never had any thought that there even could be fairies in the garden, when left to their own devices, especially if they are over the age of 7, will likely not naturally start to wonder about the fairies. People do not, by nature, question their lack of faith in the supernatural. It takes significant effort to adopt a set of beliefs.

And yes, there are people who question their faith in their god or gods and weather the storm - they keep on believing until the day of their death, and there are people who have been completely unexposed to any form of spirituality who do start to seek something on their own, and there are people who, with the effort of family and friends, genuinely convert to all manner of religions.

But it is far easier to lose faith. An Atheist that doesn't put in an effort or give a damn will not wake up one day a Christian. A Christian that doesn't put in an effort to maintain those beliefs, however, might just wake up one day an Atheist.
