Luke 1:26-38- n the sixth month the angel Gabriel was sent from God to a city of Galilee named Nazareth, 27 to a virgin betrothed to a man whose name was Joseph, of the house of David. And the virgin’s name was Mary.28 The angel came to her and said, “Greetings, you who are highly favored. The Lord is with you. Blessed are you among women.”
29 When she saw him, she was troubled by his words, and considered in her mind what kind of greeting this might be. 30 But the angel said to her, “Do not be afraid, Mary, for you have found favor with God.31 Listen, you will conceive in your womb and bear a Son and shall call His name JESUS.
32 He will be great, and will be called the Son of the Highest. And the Lord God will give Him the throne of His father David,33 and He will reign over the house of Jacob forever. And of His kingdom there will be no end.”
34 Then Mary said to the angel, “How can this be, since I do not know a man?”
35 The angel answered her, “The Holy Spirit will come upon you, and the power of the Highest will overshadow you. Therefore the Holy One who will be born will be called the Son of God. 36 Listen, your cousin Elizabeth has also conceived a son in her old age. And this is the sixth month with her who was declared barren. 37 For with God nothing will be impossible.”
38 Mary said, “I am the servant of the Lord. May it be unto me according to your word.” Then the angel departed from her.never had a man.” 35 The angel said to her, “The Holy Spirit will come on you. The power of the Most High will cover you. The holy Child you give birth to will be called the Son of God.
The angel Gabriel personally delivered a message to the virgin Mary from God in heaven that she would be the Mother of the "Savior" of the World.
This New Testament visitation by the Angel Gabriel to the Virgin Mary sets into motion the fulfillment of Isaiah's prophecy that was prophesied by the Prophet hundreds of years prior to it happening. Isaiah prophesied concerning Mary what the Angel Gabriel is delivering to her through this text.
The Prophet Isaiah prophesied that a virgin shall conceive and bare a son and shall call His name "Immanuel," God with us.
The Word of God is true! It will not return unto Him void for it shall go forth and accomplish what God said it will do.
God gave you a promises? Wait on Him!
