I used to believe that too, then after further study I saw that was not the case at all.
Here is a good place to start:

To me, at least, my doubts about the religion I was raised and never really believed, caused me to research and study BOTH sides of the arguments, not looking for what I WANTED to find, but just looking to see what was really there.
It ( the research) gave me and strengthened my faith.
I do NOT agree with organized religion, I think that it has caused more bad than good simply because it places MAN above God or at least in the place of God.
I think people should be free to seek and find their own way in the world and I believe that, given time and a desire for discovering the truth, eventually all people will realize that THEY are the key to finding God and not any organization.
