God could have chosen from among hundreds of girls or young women to be the mother of God’s only Son on earth. Why did he choose a young teenager from a wide spot in the road village, Nazareth. They said “Nothing good ever comes from Nazareth.”
But now we watch The Creator of the universe, Almighty God, pick this nondescript teenager to be the mother of the Savior of the world. And a virgin to boot.
Jesus’s mother had to be a virgin. It could have happened no other way. Remember with the first bite of the apple in Genesis Adam and Eve died spiritually. So every man, woman and child born from Adam and Eve’s union were born into sin.
“we too all formerly lived in the lusts of our flesh, indulging the desires of the flesh and of the mind, and were by nature children of wrath, even as the rest.” Ephesians 2:3
We all were at one time born into the world children of wrath and were deserving of death.
Jesus came into the world to give us His life. He had God’s love and eternal life to give anyone who would believe in Him and accept the free gift of eternal life Jesus was willing to give them.
“God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.” John 3:16.
So, if Jesus was born to anyone but a virgin, he wouldn’t have had God’s eternal life to give away. And we would all die without God.
