Michael W. Smith 

Or the original Latin version.



Agnus Dei, qui tollis peccata mundi, miserere nobis.
Agnus Dei, qui tollis peccata mundi, miserere nobis.
Agnus Dei, qui tollis peccata mundi, dona nobis pacem.
which means:

    Lamb of God, you who takes away the sins of the world, have mercy upon us.
    Lamb of God, you who takes away the sins of the world, have mercy upon us.
    Lamb of God, you who takes away the sins of the world, grant us peace. 
Truly our Lord Jesus is worthy... let us remember this this Sunday.
