Being a (White) Baptist leading a black gospel quartet and attending an other-than-me all black Baptist church, I can ask some friends. I can just about guarantee that some of them are going to find it offensive. The simplest thing is to change the words in that line. I heard the song sung in a white Lutheran Church I was a member of, and they didn't have the razors line in there, from what I remember. Have 'em check something else. Like their pride. I'll get back to you on this one, or you can e-mail me at gospelmessengers@msn.com.
