“[Jesus] will be great and will be called the Son of the Most High. And the Lord God will give to him the throne of his father David, and he will reign over the house of Jacob forever, and of his kingdom there will be no end.”
Luke 1:32-33
King and kingdom will never end.
“And Mary said to the angel, ‘How can this be, since I am a virgin?’ And the angel answered her, ‘The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be called holy – the Son of God.'”
Luke 1:34-35
Her demeanor was humble and meek, and Gabriel took no issue with answering her inquiry. His answer resounds with the OT picture of the glory of God hovering/brooding over the tabernacle. That’s the picture he gives of the Most High’s shadowing of her life.
“‘And behold, your relative Elizabeth in her old age has also conceived a son, and this is the sixth month with her who was called barren. For nothing will be impossible with God.'”
Luke 1:36-37
If all of this seemed impossible for Mary to believe, verse 37 shows her that even her barren and old relative was with child. Impossible is never a descriptor of the Most High God.
