I believe in God, the Father almighty,
creator of heaven and earth.
I believe in Jesus Christ, his only Son, our Lord.
He was conceived by the power of the Holy Spirit and born of the virgin Mary.
He suffered under Pontius Pilate,
was crucified, died, and was buried.
He descended to the dead.
On the third day he rose again.
He ascended into heaven,
and is seated at the right hand of the Father.
He will come again to judge the living and the dead. I believe in the Holy Spirit,
the holy catholic Church,
the communion of the saints,
the forgiveness of sins,
the resurrection of the body,
and the life everlasting. Amen.

In the sixth month, the angel Gabriel was sent by God to a town in Galilee called Nazareth, to a virgin engaged to a man named Joseph, of the house of David. The virgin’s name was Mary. And the angel came to her and said, “Greetings, favored woman! The Lord is with you.” But she was deeply troubled by this statement, wondering what kind of greeting this could be. Then the angel told her, “Do not be afraid, Mary, for you have found favor with God. Now listen: You will conceive and give birth to a son, and you will name him Jesus. He will be great and will be called the Son of the Most High, and the Lord God will give him the throne of his father David. He will reign over the house of Jacob forever, and his kingdom will have no end.” Mary asked the angel, “How can this be, since I have not had sexual relations with a man?”

Luke 1:26-34
 

The angel replied to her, “The Holy Spirit will come upon you, and the power of the Most High will overshadow you. Therefore, the holy one to be born will be called the Son of God. And consider your relative Elizabeth — even she has conceived a son in her old age, and this is the sixth month for her who was called childless. For nothing will be impossible with God.” “See, I am the Lord’s servant,” said Mary. “May it happen to me as you have said.” Then the angel left her.

Luke 1:35-38
 

In the days of King Herod of Judea, there was a priest of Abijah’s division named Zechariah. His wife was from the daughters of Aaron, and her name was Elizabeth. Both were righteous in God’s sight, living without blame according to all the commands and requirements of the Lord. But they had no children because Elizabeth could not conceive, and both of them were well along in years.

Luke 1:5-7
 

In those days Mary set out and hurried to a town in the hill country of Judah where she entered Zechariah’s house and greeted Elizabeth. When Elizabeth heard Mary’s greeting, the baby leaped inside her, and Elizabeth was filled with the Holy Spirit. Then she exclaimed with a loud cry, “Blessed are you among women, and your child will be blessed! How could this happen to me, that the mother of my Lord should come to me? For you see, when the sound of your greeting reached my ears, the baby leaped for joy inside me. Blessed is she who has believed that the Lord would fulfill what he has spoken to her!”

Luke 1:39-45
 

Note that she did not say that Mary was blessed above women but among women, and certainly this is true. While we don’t want to ascribe to Mary that which only belongs to God, neither do we want to minimize her place in the plan of God. – Warren Wiersbe
 

And Mary said: My soul magnifies the Lord, and my spirit rejoices in God my Savior, because he has looked with favor on the humble condition of his servant. Surely, from now on all generations will call me blessed, because the Mighty One has done great things for me, and his name is holy. His mercy is from generation to generation on those who fear him. He has done a mighty deed with his arm; he has scattered the proud because of the thoughts of their hearts; he has toppled the mighty from their thrones and exalted the lowly. He has satisfied the hungry with good things and sent the rich away empty. He has helped his servant Israel, remembering his mercy to Abraham and his descendants forever, just as he spoke to our ancestors.

Luke 1:46-55
 

Sin is any failure to reflect God in nature, attitude, or action.
 

just as sin entered the world through one man, and death through sin, in this way death spread to all people, because all sinned.If by the one man’s trespass, death reigned through that one man, how much more will those who receive the overflow of grace and the gift of righteousness reign in life through the one man, Jesus Christ. For just as through one man’s disobedience the many were made sinners, so also through the one man’s obedience the many will be made righteous.

Romans 5:12, 17, 19
 

If Joseph was the real father of Jesus, or Mary had been sleeping around, Jesus is not spotless, not innocent, and not perfectly holy. And as a result, we have no mediator and no salvation. – Kevin DeYoung
 

He made the one who did not know sin to be sin for us, so that in him we might become the righteousness of God.

2 Corinthians 5:21
