The meaning of the name Jesus informs us of the mission of Christmas because the name Jesus means to save His people from their sins. Jesus came that first Christmas to rescue all of us from our wrongdoings.
Another name for Jesus – Emmanuel – tells us the message of Christmas. Emmanuel means God with us. God, in the form of a baby, left heaven and came to earth as a baby. Because of His death on the cross 33 years later, Emmanuel Jesus -God with us- ultimately offered us God in us the Comforter – the Holy Spirit.
