I’ll allow the Holy Spirit to tell the story through Scripture.
Now in those days a decree went out from Caesar Augustus, that a census be taken of all the inhabited earth. This was the first census taken while Quirinius was governor of Syria. And everyone was on his way to register for the census, each to his own city. Joseph also went up from Galilee, from the city of Nazareth, to Judea, to the city of David which is called Bethlehem, because he was of the house and family of David, in order to register along with Mary, who was engaged to him, and was with child. While they were there, the days were completed for her to give birth. And she gave birth to her firstborn son; and she wrapped Him in cloths, and laid Him in a manger, because there was no room for them in the inn. In the same region there were some shepherds staying out in the fields and keeping watch over their flock by night. And an angel of the Lord suddenly stood before them, and the glory of the Lord shone around them; and they were terribly frightened. But the angel said to them, “Do not be afraid; for behold, I bring you good news of great joy which will be for all the people; for today in the city of David there has been born for you a Savior, who is Christ the Lord. “This will be a sign for you: you will find a baby wrapped in cloths and lying in a manger.” And suddenly there appeared with the angel a multitude of the heavenly host praising God and saying, “Glory to God in the highest, And on earth peace among men with whom He is pleased.” When the angels had gone away from them into heaven, the shepherds began saying to one another, “Let us go straight to Bethlehem then, and see this thing that has happened which the Lord has made known to us.” So they came in a hurry and found their way to Mary and Joseph, and the baby as He lay in the manger. When they had seen this, they made known the statement which had been told them about this Child. And all who heard it wondered at the things which were told them by the shepherds. But Mary treasured all these things, pondering them in her heart. The shepherds went back, glorifying and praising God for all that they had heard and seen, just as had been told them. And when eight days had passed, before His circumcision, His name was then called Jesus, the name given by the angel before He was conceived in the womb. (Luke 2:1-21, NASB)
For while we were still helpless, at the right time Christ died for the ungodly. For one will hardly die for a righteous man; though perhaps for the good man someone would dare even to die. But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us. Much more then, having now been justified by His blood, we shall be saved from the wrath of God through Him. For if while we were enemies we were reconciled to God through the death of His Son, much more, having been reconciled, we shall be saved by His life. (Romans 5:6-10, NASB)
“For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life. For God did not send the Son into the world to judge the world, but that the world might be saved through Him. He who believes in Him is not judged; he who does not believe has been judged already, because he has not believed in the name of the only begotten Son of God.” (John 3:16-18, NASB)
