Give the Lukan account of the birth of Jesus and the the lessons that can be learnt from the circumstances of his birth

Mary, a virgin, was
betrothed to a man named Joseph. The angel of the Lord had told Mary that she
would bear a son whose name would be Jesus. The angel explained that the Holy
Spirit would come upon Mary and that the power of the Most High would
overshadow her. The child to be born would be called holy, the Son of God. Soon
after the encounter Mary was conceived of the Holy Spirit. When the time for
her to be delivered approached, Joseph went with her down to Bethlehem in Judea.
This was because Caesar Augustus had ordered that everybody should go to his
town for a census. Joseph and Mary went to Bethlehem, the city of David for the
census, because they were of that lineage. As there was no place in the Inn,
Mary gave birth to a baby boy in a manger. Mary wrapped the child in swaddling
clothes and laid him in a manger. The shepherds were told about the birth of
Jesus in the city of David by the angels, just as the heavenly Host glorified
God: Glory to God in the highest and on earth peace among men with whom He is
pleased. And they went to see the child and everything was as the angel said.
And the shepherds returned, glorifying and praising God for all they had heard
and seen,  

Lessons:  

1. One important lesson is that the humble
   nature of one’s birth does not affect one’s greatness in life, 
2. With
   God, all things are possible. Mary, a virgin, was conceived of the Holy Spirit
   when in human perspectives would have been impossible, 
3. We should
   take our civic responsibility seriously. Joseph carried out his civic
   responsiblity by taking Mary to Bethlehem in deference to the Roman authorities
   concerning census. God can use people of humble birth to achieve His purposes.
