A) Can you be born with a faith or do you learn to believe as you go on living?In other is faith a natural process and if so where do those who don't have faith fit in?
b) Is it important to have a faith in a god?
I personally think faith is a personal act and comes from within.
I am not sure you can teach someone to believe and so it is up to the individual whether they acquire a faith. any faith or not.
In the grand scheme of thing I don't consider it essential nor proliofic not to have faith because people are and will always be different, which makes life easier and more interesting, and so are/will our faiths andeelings.
It is better to have a mix of feelings faith or no faith then to live amongst samy people samy faith.
That is my opinion.
