My carol from this year isn't necessarily a carol but I've always loved it and loved hearing my dad with various choirs sing it. As I was putting up Christmas decorations, I just started singing For Unto Us a Child is Born from Handel's Messiah. The song is based on Isiah 9:6.
The Lyrics are as follows:
For unto us a child is born,
Unto us a Son is given,
And the Government shall be upon His shoulder;
And His Shall be Called
Wonderful,
Counsellor,
The Mighty God,
The Everlasting Father,
The Prince of Peace.
