"Run, Sinner, Run"

Recently I was listening to a man talk about music, and during his talk he played several songs for us to demonstrate his point. there was one song in particular that I was rather enjoying, at least i was until the third verse that stated "Run, sinner, run. Find a hiding place" and it said this three times. I wonder about the appropriateness of having a second person, direct address statement to sinners about hiding from the wrath of God. While it is very much a reality for sinners, is it proper or worshipful to directly address them in a song and tell them to flee? Worship should honor God...to give Him praise or to speak of His attributes. Even songs that call people to worship or to holiness and repentance can be considered acceptable in a service...but can this be?

I laughed at the obscurity and what appeared to be a strange shift in the song, but then felt as though I should be singing the song in utter sadness for the sinner (rather than the slightly jovial attitude that I experienced) or be angry that it was in the song at all...that it inspired people to be like pharisees and look down on sinners.

So to summarize:
1) I question the relevance and appropriateness of such statements.
2) I question the relevance and appropriateness of directly addressing sinners in a Church service (given my biased perspective that a worship service is for the believer, not the unbeliever).
3) I question the attitude in which it was presented

So what do you think?
