Is being born with a sinful nature in of itself sinful?
The bible also states to seek wisdom and I believe that wisdom dictates that, despite what is said that all have sinned, all have not really sinned as there are apparent exceptions. The bible also says that the sun rises and sets but, in fact, does not either. Again, the bible is just stating that it is only apparent that the sun rises and sets but in reality the earth rotates on its axis and this allows for both light and darkness depending on the time of day. Very few, if any, of the children being treated at St. Jude's Children and Research Hospital have actually reached a stage where it was possible for them to commit a sin. Regardless, we all have a savior who died for our sins regardless of our age or circumstances.
