Stop building strawmen to knock down.

I never said that all people don’t have a sin nature and that all people don’t sin, with the exception of Jesus. The Bible says that ALL have sinned, which, BTW includes Mary otherwise Scripture is wrong.
But SCRIPTURE clearly says that the sin nature comes through the man. That’s why Jesus was sinless, because His father was not human with a sin nature, but God without one.
Since you obviously don’t accept the Scriptural reason why Jesus was without sin, what is YOUR reason that HE was without sin.
What Scripture can you use to demonstrate that the sin nature comes through the mother and not the father as you claim?
What part of "All have sinned and fall short of the glory of God" do you have a problem with? All means all. All men and all women. Are you playing a game? All. We get our sin nature through both our parents. Christ preserved Mary from sin, He saved her before she was born, thus she was fully human, without stain of sin; so He could be born Son of God, fully human and fully God. Why is that so hard to understand?
