聖誕歌（Joy to the world）的完整歌詞如下：
Joy to the world, the Lord is come!
Let earth receive her king;
Let every heart prepare him room,
And heaven and nature sing.
And heaven and nature sing, and every heart,
And heaven, and every creed,
For Jesus Christ is born in peace on earth,
Joy to the world!
Oh, what a day it will be!
When we go singing up the street
And show the way to all we meet.
Joy to the world!
When we tell of Jesus birth,
And find that every heart will beat in unison,
We'll be singing his praises all through every land.
Joy to the world!
