Start in Luke 1:26
"26 In 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 And he came to her and said, "Hail, O favored one, the Lord is with you!" 29 But she was greatly troubled at the saying, and considered in her mind what sort of greeting this might be. 30 And the angel said to her, "Do not be afraid, Mary, for you have found favor with God. 31 And behold, you will conceive in your womb and bear a son, and you shall call his name Jesus. 32 He will be great, and will be called the Son of the Most High; and the Lord God will give to him the throne of his father David, 33 and he will reign over the house of Jacob for ever; and of his kingdom there will be no end." 34 And Mary said to the angel, "How shall this be, since I have no husband?" 35 And the angel said to her, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be called holy, the Son of God. 36 And behold, your kinswoman Elizabeth in her old age has also conceived a son; and this is the sixth month with her who was called barren. 37 For with God nothing will be impossible."38 And Mary said, "Behold, I am the handmaid of the Lord; let it be to me according to your word." And the angel departed from her."
God shows us that he fulfills his promises. By making preparations for and bringing Jesus his son to the world, God fulfilled his old testament prophecy regarding the salvation of man.
“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 9:6 “For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace.” Isaiah 7:14
He made a promise to us and delivered, like he always does!
Watch for signs of God's preparations in your life. Even during your worst days and hardest times, God is preparing for you something great! To receive the blessings that come from God's preparation, all you have to do is believe that Jesus died on the cross for your sins, so that you may have salvation, experience his grace, and have acceptance into the kingdom of Heaven.
Pray that the Holy Spirit will reveal God's plan and direction for your life.
