The problem with the "free will" approach is that it relies upon individuals hearing the "message" and making informed decisions. What happens to those who, for whatever the reason, are not afforded the opportunity to make that decision?
What about it? Do you think no rule can have exceptions for circumstances? God doesn't expect a baby to profess or act like he expects an adult to. This doesn't mean an adult can act like a baby. People who are capable of exercising their wills are responsible for the choices they make. Children and those mentally handicapped are not.
This isn't rocket science.
