Zephaniah 3:9: Then will I turn to the people a pure language, &c

On Thee, great God, we still attend.
Till judgment shall in mercy end.
And wrath in universal grace:
The promise to Thy church is sure.
Our hearts, and lives, and language pure
Shall speak our new-Creator's praise.

Then every soul his Lord shall know,
And every spotless saint below
Perform Thy will, like those above;
We all shall think, and speak the same,
And serve our God, and praise Thy name
With perfect harmony and love.
