Answer:
the most important truth of the nativity, was that [John 3:16] "God so loved the world, that he gave his only begotten son. that whoever believes in Him shall not perish, but have eternal life." God gave his son, Jesus, to the world to SAVE it!!! =D YAY! the young Mary, who happened to be a virgin, was betrothed to Joseph, a carpenter. one day, an angel of the lord appeared to Mary and told her that she was going to be with child, and she shall call him Jesus. an angel of the lord also appeared to Joseph in a dream and told him of the news. so the holy spirit came upon Mary and caused her to become pregnant, and about the time she was to give birth, a decree came out from Caesar Augustus, that every man should go back to the place of his birth, along with his wife and children, and be counted and taxed. so Joseph took his pregnant wife Mary to Bethlehem, the city of David. it was so packed there, cuz of everybody coming in, so there were no vacancies in any of the inns. an innkeeper finally provided Mary and Joseph with a small stable at the back of the inn to stay the night in. there, the King was born, and even the animals in the stable rejoiced at the time!!! =D there is more to the story....like the shepherds in the field, and the three wise men, but i hope you will take the time to read the rest of this amazing story in the bible!! =D it can be found starting in Matthew 1:18. there are also other places that talk of that glorious night...Merry Christmas! and happy birthday Jesus! =D
