I stumbled across this song a few years before I retired. Our Praise Team sang this just before our Christmas Eve service in 2018.  A simple yet powerful affirmation of what God did for us:  “the light has come” and “we have a Saviour.”  It also tells us how we should respond:  “Come and adore Him,” “Sing with the angels” and “Tell all the world.”

A child has been given The King of our freedom
Sing for the light has come This is Christmas
|Come and adore Him And bring gifts before Him
Joy to the world  Worship the Son This is Christmas

CHORUS

This is Jesus Emmanuel Here with us tell all the world
We have a Saviour we have a Saviour
We are no longer lost  ‘Cause He has come down for us
We have a Saviour we have a Saviour

Sing with the angels And lift up your voices
|Join in the song of hope    This is Christmas

CHORUS

His love will reign forever

CHORUS

 Merry Third Day of Christmas.
