Hi
Hopeful 2
You're absolutely right, but on a christian discussion site I think it's common for believers to discuss particulars about what the Scriptures teach us and what they tell us.
I don't know whether or not Jesus had any of Mary's DNA. I'm not God, but I do know that there's a good chance that Jesus human body was created just as Adam's human body was created. Without the aid of previous human DNA. I do believe that there's a good chance that
if sin is passed through from generation to generation as the Scriptures infer, then it could possibly pass through some sort of genetic link. I don't know and the Scriptures aren't clear to tell us exactly what Jesus meant when he said that the first Adam passed sin down to all generations.
