And she will have a son and you are to name Him Jesus, for He will save His people from their sins Matthew 1:32 

“Don’t be afraid, Mary,” the angel told her,” for you have found favor with God.”  You will conceive and give birth to a son and you will name him Jesus.” Luke 1:30-31  

When God gave the name Jesus it is interesting to see that he spoke both to Joseph and to Mary. To Mary Gabriel explained all that Jesus would do as the Messiah, but to Joseph God defined the name. The name Jesus was given because God had given His Son, not only to teach us the ways of Heaven, heal our sickness, or give us a comfortable life; Jesus came to save His people from their sins. 

One of the most beautiful sounds in the entire world to each of us is the sound of our own name. We love to hear our name mentioned especially if it is linked with assurance, love or praise. The sound I want most to hear as I cross into eternity is my own name being called by God himself with the phrase “Well done good and faithful servant” Our name is what calls our attention at any moment. 
Imagine Jesus entering the world cradled in Mary’s arms in that stable in Bethlehem. One of the first words Mary and Joseph would say was, “Jesus!”  God had kept His promise to them just as He said. From that day forward every time Jesus heard His own name it would be a reminder of why He had come. When He was growing up in the home with His brothers and Mary called out, “Jesus” he would remember that he was different. God had sent Him not just to be born in the humble stable, but also one day to give His life as a sacrifice for us.
