To me the lyrics are waaaay more thna 1/2 of what I like about a song. Some of the best just for the joy of imagining this conversation:

Oh God said to Abraham, "Kill me a son"
Abe says, "Man, you must be puttin' me on"
God say, "No." Abe say, "What?"
God say, "You can do what you want Abe, but
The next time you see me comin' you better run"
Well Abe says, "Where do you want this killin' done?"
