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 heaven, and heaven and nature sing 

 

Joy to the world! The Savior ( reigns ) 
Let men their songs ( employ ) 
While（ fields ）and floods 
(Rocks）, hills and plains 
Repeat the sounding joy 
Repeat the sounding joy 
Repeat, repeat the sounding joy 

 

He rules the world with truth and grace 
And makes the nations prove  

And glories of His ( righteousness ) 
And wonders of His love 
And wonders of His love 
And wonders, wonders of His love
