"Therefore the Lord himself shall give
you a sign; Behold, a virgin shall conceive,
and bear a son, and shall call his name
Immanuel." Isaiah 7:14
The prophet Isaiah predicted 800 years
before it happened that Jesus would be
born of a virgin.
He was born of the Holy Spirit, not of
man, He was the Son of God. It was the
only way He could be our Savior.
