Luke shows us that common people were included in the story of the birth as they were bowled over by the light of God’s glory

8 And there were shepherds living out in the fields near by, keeping watch over their flocks at night. 9 An angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were terrified. 10 But the angel said to them, ‘Do not be afraid. I bring you good news that will cause great joy for all the people. 11 Today in the town of David a Saviour has been born to you; he is the Messiah, the Lord. 12 This will be a sign to you: you will find a baby wrapped in cloths and lying in a manger.’

13 Suddenly a great company of the heavenly host appeared with the angel, praising God and saying,

14 ‘Glory to God in the highest heaven, and on earth peace to those on whom his favour rests.’

15 When the angels had left them and gone into heaven, the shepherds said to one another, ‘Let’s go to Bethlehem and see this thing that has happened, which the Lord has told us about.’

16 So they hurried off and found Mary and Joseph, and the baby, who was lying in the manger. 17 When they had seen him, they spread the word concerning what had been told them about this child, 18 and all who heard it were amazed at what the shepherds said to them. 19 But Mary treasured up all these things and pondered them in her heart. 20 The shepherds returned, glorifying and praising God for all the things they had heard and seen, which were just as they had been told

Luke 2:8-20[New International Version]

The light shines in the darkness, but the darkness has not understood it” (John 1:5), or “has not been able to overcome it.”

In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was with God in the beginning. 3 Through him all things were made; without him nothing was made that has been made. 4 In him was life, and that life was the light of all mankind. 5 The light shines in the darkness, and the darkness has not overcome it.

6 There was a man sent from God whose name was John. 7 He came as a witness to testify concerning that light, so that through him all might believe. 8 He himself was not the light; he came only as a witness to the light.

9 The true light that gives light to everyone was coming into the world. 10 He was in the world, and though the world was made through him, the world did not recognise him. 11 He came to that which was his own, but his own did not receive him. 12 Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God – 13 children born not of natural descent, nor of human decision or a husband’s will, but born of God.

14 The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth.

15 (John testified concerning him. He cried out, saying, ‘This is the one I spoke about when I said, “He who comes after me has surpassed me because he was before me.”’) 16 Out of his fullness we have all received grace in place of grace already given. 17 For the law was given through Moses; grace and truth came through Jesus Christ. 18 No one has ever seen God, but the one and only Son, who is himself God and is in the closest relationship with the Father, has made him known.

John 1:1-18 [New International Version]

Isaiah begins this prophecy stating that amid spiritual darkness, the blackness that plagued Israel and plagues us today, is pierced by the light of God’s salvation.

Nevertheless, there will be no more gloom for those who were in distress. In the past he humbled the land of Zebulun and the land of Naphtali, but in the future he will honour Galilee of the nations, by the Way of the Sea, beyond the Jordan –

2 The people walking in darkness

have seen a great light;

on those living in the land of deep darkness

a light has dawned.

3 You have enlarged the nation

and increased their joy;

they rejoice before you

as people rejoice at the harvest,

as warriors rejoice

when dividing the plunder.

4 For as in the day of Midian’s defeat,

you have shattered

the yoke that burdens them,

the bar across their shoulders,

the rod of their oppressor.

5 Every warrior’s boot used in battle

and every garment rolled in blood

will be destined for burning,

will be fuel for the fire.

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 Counsellor, Mighty God,

Everlasting Father, Prince of Peace.

7 Of the greatness of his government and peace

there will be no end.

He will reign on David’s throne

and over his kingdom,

establishing and upholding it

with justice and righteousness

from that time on and for ever.

The zeal of the Lord Almighty

will accomplish this

Isaiah 9:1-7 [New International Version]
