NWT LUKE CHAPT 1
41 Well, as Elizabeth heard the greeting of Mary, the infant in her womb leaped, and Elizabeth was filled with holy spirit 42 and loudly cried out: “Blessed are you among women, and blessed is the fruitage of your womb! 43 So how is it that this privilege is mine, to have the mother of my Lord come to me?
1] When Mary visited Elizabeth, neither had given birth, yet Mary was already the mother of Jesus and Elizabeth was mother of John the baptist. So according to the bible, you are a mother when you are pregnant, prior to giving birth.
2] While visiting, Elizabeth was filled with the Holy Spirit and was with John the baptist, Jesus and Mary but gives honor to Mary specifically by asking how this privilege came to her that Mary would visit her.
