Make sure that a non-Christian will have no idea what you're talking about. In fact, if it's vague enough you should be able to get non-Christians to sing along without knowing what they are singing. Check out "U2 Yahweh live from Chicago" on youtube and you'll see what I mean.

Seriously though, aren't the song writers selling what we're buying? If today's audiences/congregations were a little more musically literate, wouldn't they demand actual music? Aren't these types of worship ditties exactly the reason that so many of us musicians (I play bass and trumpet) insist on making a distinction between "singers" and "musicians". My kids will all be musically literate and will be able to know good music when they hear it, regardless of it's source or content.

It used to be that the Church is where the great music was. It seems that the Church has now left great music to others. I say it's time to bring it back to the Church!
