Yes, actually. I used to be an atheist, and it was the works of apologists that let me to believe in Christianity. I know that many atheists can't fathom the fact that a rational person could disagree with them, and I will probably now be looked upon as indoctrinated and deluded, but questioning, disagreement, and debate all helped me to find my faith and strengthen it.
I think part of this is due to the fact that I come from a Jewish tradition, where debate and argument are part of the faith.
