Luke 2: 8-14, read:
And there were in the same country shepherds abiding in the field, keeping watch over their flock by night. And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid. And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. For unto you is born this day in the city of David a Saviour, which is Christ the Lord. And this [shall be] a sign unto you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger. And suddenly there was with the angel a multitude of the heavenly host praising God, and saying, Glory to God in the highest, and on earth peace, good will toward men.
Jesus came to earth to become the sacrificial Lamb, and Save us from the sin that is in this world and ourselves. He was born so that we could live eternal. He was born so that we have Hope, Joy, Peace even in hard, trying and sad times. He is a personal Lord and Savior.
For God so loved the world, that He gave his only begotten Son, and whosoever believes in Him, shall not perish, but have everlasting life.
