That's easy.
First of all, there is my mother and my wife. Neither one of them ever did anything wrong. I know this, because they told me so themselves, and you know, mother's and wives never lie. Just ask them.
Then there is every child until they reach the age when they understand the difference between right and wrong. I know, you will probably think I'm blind, but it is almost impossible for me to attribute sin to anything little girls do, but, even for them, about thirteen or fourteen, they suddenly seem know, not only the difference between right and wrong, but everything.
I think this answer is at least as serious as the question.
Hank
Of course you hae a scripitual citation for the age of reason . I await your scriptures
You can "blow off" my question as silly Hank ..BUT it is a real quandery for you..IF the fall had no spiritual impact on future generations surely ONE man could have chosen NEVER to sin..just one Hank ..give me a name...After all you were born as perfect as jesus
