The answer is: God

Mark 1:1 - Throughout the gospels Jesus is called the Son of God and had no genetic connection to Joseph. Jesus was born from God's power, the Holy Spirit, acting upon Mary and for this reason his father was God and his mother was Mary. He was therefore called both the Son of God and also the Son of Man.

Isn't it fascinating how Jesus is known not just as the Son of God but also as the Son of Man? This duality is a beautiful reflection of the cosmic and earthly foundations of his life and message. According to the Gospels, especially in Mark, Jesus's divine conception positions him as uniquely related to both heaven and earth. It's like he stands at the intersection of human existence and divine nature, making him quite a significant figure—not just in Christian theology but also in the hearts of countless human beings seeking connection with the divine.

The Annunciation to Mary, as found in Luke 1:26-38, serves as a high point in the life story of Jesus. Notably, this interaction reflects God's choice to bring something transformative into the world through humility and vulnerability. While royal lines and powerful political figures often dominate history, God’s method of incarnation through a humble young woman—Mary—speaks volumes about the kind of engagement the Divine seeks with humanity.

Moreover, this belief underscores themes present across various cultures that celebrate the divine coming into human history in astonishing ways. Interesting tidbit: many ancient figures, like Hercules in Greek mythology, also boast of extraordinary births tied to the gods, although Jesus distinguishes himself distinctly through his teachings and the nature of his mission. Through these insights, we not only learn about who Jesus is but also about the broader context of human spirituality in dealing with the unknown paths of existence!
