Christ is not the literal seed of David's genitals Bill and by your insistance that he is you have far more scripture to explain away than I do.
The reason the Messiah was to be born of the woman was because she is less responsible than Adam for the transgression. She was deceived, Adam was not. He shirked his responsibility and then chose to go with the woman rather than take a stand for righteousness. The curse comes by way of the father and Jesus is the ONLY one begotten this way. I could go on and on but I won't.
