This might help.
I pray it does like it helped me to understand what we are dealing with.
Interesting point I learned from my pastor...
Therefore, just as sin entered the world through one man, and death through sin,
and in this way death came to all people, because all sinned. Romans 5:12
The English translation leaves us wondering. The Greek does not.
The Greek has a definite meaning.
It is saying that when Adam sinned? We all sinned in that one point in time.
Adam sealed our fate when he sinned..
His fallen nature was passed down to the woman by means of his sperm.
For? In Adam all die.
What about the woman's ovum? The ovum does not transfer the fallen nature.
That is why Jesus had to have no human father.
That is why Genesis 3:15 is specific in its wording that the Messiah would come by means of the "seed of the man."
Not the man's seed.
Jesus could have no human father for that reason. The man's sperm would pass down the sin nature.
