The Holy Spirit gave Elizabeth divine revelation into the miracle of Mary and her unborn child. Elizabeth then bore witness and confirmed Mary’s faith, for it states in verse 45, “Blessed is she who has believed that what the Lord has said to her will be accomplished.” This affirmation was what Mary needed, and during the 3 months she stayed with Zechariah and Elizabeth she was encouraged and strengthened by their kind, wise words…not only marveling at the miracle happening within Elizabeth, but the ever-growing miracle inside herself.
