God was very kind to Mary after Gabriel appeared to her, by providing a sister to hurry to see to be edified by. Elizabeth like Zachariah and john, was filled with the Holy Spirit and with that filling she prophesied to Mary a message of hope and assurance. We too, because of God's kindness to us, have brethren filled with the Holy Spirit to go to and hear prophetic words of hope and assurance. May we too believe in the fulfillment of what we have been promised.
