All lands and nations offerings bring

4 Oh, may his holy church increase,
his Word and Spirit still prevail,
while angels celebrate his praise
and saints his growing glories hail.
5 Loud hallelujahs to the Lamb
from all below and all above!
In lofty songs exalt his name,
in songs as lasting as his love.
