It is about what God did in Abraham's life. Thank you.

So, Mary had an immaculate husband and conception. The thing about conception is that it is always a miracle. There are stories of women leaving certain operas dedicated to the Lord and becoming pregnant. There are stories of women leaving church or bowling matches and becoming pregnant with inspiration although they did not have any relations to ignite the intercourse. Some women have had conversations with people and have become pregnant as the conversation revealed a truth and a knowledge of the woman's soul. Joseph was obedient to his calling as Mary's husband. There is no doubt that whether or not you are having intercourse and enjoying your conjugal rights in a betrothal that the eventual conception could be that of the Lord's and Lord's alone. Hanna in the old testament knows and so does Elizabeth; the wife of Zacharias. It is no less of a miracle although we are asked to read something else into the English translation more than 2000 years later; that Mary was certainly a virgin, they did not enjoy any conjugal rights in a betrothal and she became pregnant with an immaculate conception. This is the only way to read it and is the only answer since There is no need to doubt immaculate conception in the life of a virgin or in the life of a woman who is married, is not a virgin and who desires a child. God is.  God is conception. He is immaculate.  Both conceptions in either case are both miracles and immaculate whether or not they are virgins and nobody did say Mary was the only woman in God's power or in His word from the day of Abraham going forward to enjoy an immaculate conception. In fact, the knowledge of Zachariah's and Elizabeth's conception down the road from where Mary lived, albeit in their infertile years over 40 years of age( the equivalent of 60+ years of age) confirmed the truth of God's power in conception, his evidence and his presence as He did in Genesis.  It is also confirmation  of something else; His intention in His message in bringing Yeshua to fulfill the law and the prophets in His teaching.  Because Abraham could not have children, Sarah certainly had an immaculate conception.  May had an immaculate conception.  The bible did not say that Mary had the only one or the first one in biblical history as we understand the word immaculate. In the Catholic dictionary immaculate means "free from sin" or "free from moral stain".   Sarah had an immaculate conception as did Mary.   It is about what God did in Abraham's life. Did you know Abraham lived in Africa? Did you know Moses lived in Africa? Did you know Yeshua lived in Africa?  Everybody is accepted and some of these patriarchs had African wives and half African children.  Thank you!
