Therefore the Lord himself will give you a sign: The virgin will be with child and will give birth to a son, and will call him Immanuel. (Isaiah 7:14)
At that time Mary got ready and hurried to a town in the hill country of Judea, where she entered Zechariah’s home and greeted Elizabeth.
When Elizabeth heard Mary’s greeting, the baby leaped in her womb, and Elizabeth was filled with the Holy Spirit. In a loud voice she exclaimed: “Blessed are you among women, and blessed is the child you will bear!
But why am I so favored, that the mother of my Lord should come to me?
As soon as the sound of your greeting reached my ears, the baby in my womb leaped for joy. Blessed is she who has believed that what the Lord has said to her will be accomplished!” (Luke 1 :39-45)
And this is the testimony: God has given us eternal life, and this life is in his Son.(1 John 5:11)
