In this day and age this particular question is being discussed quite a bit in Christian circles. For those who are wrestling with this particular question, I found an article that I found quite helpful.

Here is an excerpt from that article.

At least one thing has become clear to me as I have been looking at this question rather closely over the last year. This question really isn’t a new one. At the end of the day, the question forces us back onto terrain that has been well-traversed by theologians over the past 20 centuries. The answer really does come down to one’s anthropology.
If you view human nature as a tabula rasa and if you reduce sin/sinfulness to one’s behavior—that which one chooses to do—then you are going to answer the question a certain way. If however, you regard the human condition as fundamentally flawed—that we are sinful not just in our choices but also in our nature—then you are going to answer the question a different way. And that difference goes back at least as far as Augustine and Pelagius.
