Behold Your King Advent - Week 1: Day 2

Hymn
Scripture Reading
Genesis 49:10
Narrative Reading
Luke 1:39-56
Devotional Reading
A pregnant Mary arrives in the home of her pregnant cousin, Elizabeth. Immediately, Elizabeth and her unborn baby (John) recognize that the child growing in Mary’s womb is their Lord, “who am I that the mother of my Lord should come to me?”.
Jesus’ rule and Lordship was promised and prophesied. His kingship is inaugurated in the recognition by Elizabeth and her unborn child. The scepter and staff spoken of in Genesis 49:10 are symbolic of His kingly authority. The tribute promised to king Jesus is the inheritance of His people. Elizabeth and John are among the first of this inheritance.
Questions
Why did the baby (John) leap for joy when his mother, Elizabeth, heard the voice of Mary?
In Luke 1:47 Mary calls God her savior. In verse 49 she says, “He who is mighty has done great things for me.” What mighty thing has God done for Mary? How is He her savior?
If the scepter and staff are symbolic of Jesus’ eternal authority, how does Mary’s prayer contrast Jesus’ rule with earthly rulers?
