Luke 1:35
The angel answered, the Holy Spirit will come on you, and the power of the Most High will overshadow you. So the holy one to be born will be called the Son of God — the two-part answer: the Holy Spirit will come on you (the divine creative energy, echoing Genesis 1:2 and the Spirit hovering over the waters) and the power of the Most High will overshadow you (episkiasei, the same word for the Shekinah cloud overshadowing the tabernacle in Exodus 40:35). The result: the holy one to be born will be called the Son of God. The title is established before the birth — not earned by achievement but constituted by origin.
