In writing the book, “The Nightmare of Atheism,” one chapter is called “Is Jesus God?”
Seven Evidences are shown to prove Jesus is God. The fifth Evidence is called “The Evidence of the Virgin Birth.” This is the “sneak-peak” into that discussion:

The Evidence of the Virgin Birth
God, through Moses, wrote in Genesis 3:15 “And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.”
Point: Man carries the seed, not the woman, yet it says “her seed.”

700 years before Jesus was born, Isaiah prophesied in Isaiah 7:14 “Therefore the Lord himself shall give you a sign; Behold, a virgin (Almah) shall conceive and bear a son, and shall call his name Immanuel.”

Both Matthew and Luke provide detailed accounts of the Virgin Birth and shows its fulfillment. For Jesus (Yeshua) to be The Messiah, this had to happen.

There are two Hebrew words that used as “Virgin” - almah and bethulah. The word “Almah” is the word used in Isaiah 7:14. It means a young woman of marriageable age. Isaiah, through the Holy Spirit, used this word, not ‘Bethulah’. Why? It was because both ideas of virgin and marriageable age had to be combined into one word. It would meet the historical situation and the prophetic concept centering on a Virgin-born Messiah.

The word “Virgin” in Greek is ‘parthenos’, which means “a Virgin, marriageable maiden or young married woman, a pure Virgin.” When the Jewish translators of the Septuagint, completed around 280-246BCE in Alexandria, translated Isaiah 7:14 into Greek, they used the Greek word ‘parthenos’. To them, Isaiah 7:14 meant that the Messiah’s mother would be a Virgin.

Many people deny the Virgin Birth on the grounds that it’s biologically impossible. That IS THE WHOLE POINT! It IS impossible! That makes the Virgin Birth a “sign.” If it was not a miracle, it would not be a “sign.”

It would be more difficult to believe God became a man by the natural reproductive process of humans than to believe Jesus was conceived supernaturally. They point to the fact that the Bible is true.

The Jewish nation is also a miracle and a sign. It was a miracle for Sarah to conceive in her old age, and Isaac became the sign of the start of the Jewish nation. Which is the miracle: Sarah giving birth at the Age of 90 or a Virgin Birth? Doctors will tell you it is both.

If what God says about the Gentile nations became true, then it’s also true about what it says about Sin, Eternal Life and Salvation. If God judged people for rejecting him in the past, He would also judge people who reject Him in the future.

C. S. Lewis applied these concepts to the virginal conception of the Messiah. He stated that is the zygote was made by the Holy Spirit’s action on Mary’s ovaries, i.e. an addition to the system. But after that, the embryo developed in the normal manner.

(AQ) If a miracle of a Virgin Birth cannot happen, can you give a different explanation how the Jewish nation exists without the miracle of Isaac’s Birth?
