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.  Luke 2: 10-11
An angel spoke these words to shepherds in the fields outside Bethlehem on the day Jesus was born. The shepherds were awestruck and excited by the news that this newborn baby was to be a Saviour for God’s people.
In Bible times, any person who rescued others from danger was called a savior or deliverer. For example, the judges of Israel whom God raised up to deliver His people from oppression by their enemies were called “saviours”. But the only true Saviors in a spiritual sense are God the Father and God the Son, both of whom are called by this name many times throughout the Bible.
The name that Mary and Joseph gave their firstborn Son expresses His work as Savior. Jesus means “God Is Salvation.” From the very beginning it was clear that His purpose was to do for us what we could not do for ourselves-deliver us from the bondage to sin and death. 
The phrase “all people,” in the message of the angels to the shepherds, shows that Jesus was God’s gift to the entire world. The universal nature of Christ’s redemptive work is expressed by two other “Savior” titles in the New Testament-Saviour of All Men (1 Timothy 4:10) and Saviour of the World (1 John 4:14).
