Lord Jesus Christ birth was unique and beyond natural realms. Virgin Mary was betrothed to Joseph, while she was conceived by the Holy Spirit. Joseph indeed wanted to divorce or put her off, but did not as angel spoke to him. The new born baby is Lord Jesus Christ. With a faint imagery it is possible to explain virgin birth.
“An 11-year-old reticulated python named Thelma produced six female offspring in June 2012 at the Louisville Zoo in Kentucky, where she lives with another female python, Louise. No male had ever slithered anywhere near the 200-pound (91-kilogram), 20-foot-long (6 meters) mother snake. New DNA evidence, published in July in the Biological Journal of the Linnean Society, revealed that Thelma is the sole parent, said Bill McMahan, the zoo's curator of ectotherms, or cold-blooded animals.”
Lord Jesus Christ incarnation is important to understand God’s love for humanity. God sent his Son who is Divine as well as Human that he could die for the Sin of humanity and rise again to live for evermore. Lord Jesus did not have a human father, so he is Holy and worthy to die as propitiation for sins of humanity.
The supernatural conception of Lord Jesus Christ testifies him as Son of God, only eligible Savior of Humanity and Lord of whole creation.
