When Elizabeth heard Mary’s greeting, the child leaped in her womb. And Elizabeth was filled with the Holy Spirit and exclaimed with a loud cry, “Blessed are you among women, and blessed is the fruit of your womb. And why has this happened to me, that the mother of my Lord comes to me? (Luke 1:41–43, NRSV)
John’s first prophecy is to leap with joy in his mother’s womb when he first comes in contact with Jesus.
Elizabeth prophesies as well. She calls Jesus the Lord in her words to Mary.
Jesus is Lord. He was then and he is now. One day, every person will bow down to him and acknowledge his kingship. John and Elizabeth were ahead of the curve.
