Mine eyes have seen the glory
Of the coming of the Lord
He is trampling out the vintage
Where the grapes of wrath are stored
He hath loosed the fateful lightning
Of His terrible swift sword
His truth is marching on
[Chorus]
Glory, Glory, Hallelujah!
Glory, Glory, Hallelujah!
Glory, Glory, Hallelujah!
His truth is marching on
In the beauty of the lilies
Christ was born across the sea
With a glory in his bosom
That transfigures you and me
As he died to make men holy
Let us live to make men free
While God is marching on
[Repeat Chorus]
His truth is marching on
I have always though that this song is referring to Christ's appearance in the Jezreel Valley. The site where the final battle of the end of times(Armageddon)will take place, when God will destroy his enemies.
