The version of the song published in the current (1985) hymnal of the Church of Jesus Christ of Latter-day Saints uses the Phelps text except for the first two lines, which reflect Watts' original words.
And saints their songs employ: While fields and floods, rocks, hills and plains, Repeat the sounding joy.
No more will sin and sorrow grow, Nor thorns infest the ground; He'll come and make the blessings flow Far as the curse was found.
Let men their songs employ; While fields and floods, rocks, hills and plains Repeat the sounding joy.
He rules the world with truth and grace, And makes the nations prove The glories of His righteousness, And wonders of His love.
