Well, when you say it like that..
But I happen to believe that Jesus was indeed God's seed..
but also had the humanity of Mary while He walked here. To me, He had to have the potential to sin, as she did, as we all do....the GREAT salvation hangs on the truth that Adam sinned and the Last Perfect Adam overcame sin....for us all.
To be truthful BOL, most of these kind of discussions I don't understand,
and I wouldn't even dare to say 'who has sinned'...not my business...
I do have to take on board
@bbyrd009 argument that if Mary was perfect before birthing Jesus , then she must have been the only one ever!
Jesus came to take our punishment inherited through Adam....Jesus came to take that punishment for us
all...including Mary.
If Mary could attain the perfection that no one ever had, not even John The Baptist..no one...they bbyrd009 has a good point...why on earth Did God send ( Come in ) Jesus!! ?
I have no idea...as I say, most of it goes over my head, too complicated for me to work out.
