There are some very interesting links between Judeo-Christian and Islamic traditions about Jesus (but that's another topic I guess).
This is something which is very relevant in today's world.
The concept of virgin birth due to divine intervention into the womb of Mary is really quite an abhorent speculation. This is another of those definitive issues which persuaded me that the Bible is a man made myth. While I am still inclined to think that Jesus did exist, and was a man, and a good man, I have no intrinsic faith in the words ascribed to him, other than that they stand or fall on their own merits.
JW's believe that Jesus is divine. The WTBTS believes that Jesus is not God, but that God implanted his seed in Mary's womb, literally.
As for the gospel stories about his birth and death, these are in terms of Christianity given far more importance than the teachings ascribed to him - such as love thy enemies, turn the other cheek, etc which are routinely ignored.
