There is a river that runs from the mountains
That one river is all rivers
All rivers are that one

There is a tree that stands in the forest
That one tree is all forests
All trees are that one

There is a flower that blooms in the desert
That one blossom is all flowers
All flowers are that one

There is a bird that sings in the jungle
That one song is all music
All songs are that one
[ Lyrics from: http://www.lyricsfreak.com/j/john+denver/amazon+let+this+be+a+voice_20492840.html ]
It is the song of life
It is the flower of faith
It is the tree of temptation
It is the river of no regret

There is a child that cries in the ghetto
That one child is all children
All children are that one

There is a vision that shines in the darkness
That one vision is all of our dreams

It is a vision of heaven
It is a child of promise
It is the song of life
It is the river of no regret

Let this be a voice for the mountains
Let this be a voice for the river
Let this be a voice for the forest
Let this be a voice for the flowers
Let this be a voice for the ocean
Let this be a voice for the desert
Let this be a voice for the children
Let this be a voice for the dreamers
Let this be a voice of no regret
