Some of those words are hard to understand, all right.

As I hear them (on the 1947 Anthology of American Folk Music)
Kind friends, I want to tell you,
Because I love your soul:
No doubt you've been converted,
But you ain't ever been told.
Some people they'll try to fool you.
They got nothing else to do,
But Jesus Christ, my saviour,
He got better things for you.
