This one will be great and will be called Son of the Most High; and Jehovah God will give him the throne of David his father,

Luke 1:26-33.

Because of birth through Mary he was to be called the son of “David his father.” Accordingly, Jehovah God would give him the throne or royal seat of King David.

But how, and why, could he be called “Son of the Most High”? This one would not be the Most High God himself, who is Jehovah, but would be a Son of that Supreme One; and yet, how?

16. In answer to Mary’s inquiry as to how this could take place, what did Gabriel say?

¹⁶ Mary herself inquired about this, saying: “How is this to be, since I am having no intercourse with a man?” Gabriel answered: “Holy spirit will come upon you, and power of the Most High will overshadow you. For that reason also what is born will be called holy, God’s Son. And, look! Elizabeth your relative has also herself conceived a son, in her old age, and this is the sixth month for her, the so-called barren woman; because with God no declaration will be an impossibility.”—Luke 1:34-37.

Rather, the Almighty God, the heavenly Father, by means of his holy spirit, transferred the life-force of his chosen heavenly son from the invisible spirit realm to the egg cell in Mary’s body and fertilized it. In this way Mary became pregnant, and the child conceived in her was “holy.” It was indeed what the angel Gabriel called it, the “Son of the Most High.”—Luke 1:32.
