You said, “I always thought words like that could inspire men to storm the gates of hell.......” (The Battle Hymn of the Republic)
I believe we still can.
In most if not all hymnals, the third verse of “The Battle Hymn of the Republic” is left out:
I have read a fiery gospel writ in burnished rows of steel:
“As ye deal with my contemners, so with you my grace shall deal;
Let the Hero, born of woman, crush the serpent with His heel,
Since God is marching on.”
