Taxicab Messiah - Kidney Thieves

TAXICAB MESSIAH 

My god loved the whores and babies 
My god never noticed a sin 
My god grew and killed the daisies 
My god threw the towel in 

My god is weird, my god is scared 
My god paints a pretty picture of fear 
He's driving in gear.

One day got sick of hailing Mary's 
Hailed you, got the door and slid on in 
Told me you were good a fortune telling 
Said too much, threw the towel in 

Paid for my ride

Told him we could take the long way 
Held on to everything he said 
Wanted insight or an answer 
Pointed the rear-view at my head

All in all, what does it mean?
