We are not of this world....or at least we shouldn't be

I love Christian music. I love all types of Christian music, yes even rap. I actually love rap even though I can't do it. Much to the shame of my two wonderful daugthers, I have tried. It wasn't pretty. One of the most poplar Christian groups during the 80's was a group called Petra and they had a really good song called "Not of this World." Here are the opening lyrics:
We are Pilgrims in a strange land
We are so far from our homeland
With each passing day it seems so clear
This world will never want us here
We're not welcome in this world of wrong
We are foreigners who don't belong
We are strangers, we are aliens
We are not of this world
Here is a youtube.com video to the song: This version has a great two minute intro. I love it.

One of the Bible verses they use is I Peter 2:11 which says, "Beloved, I urge you as sojourners and exiles to abstain from the passions of the flesh, which wage war against your soul."
One of the reasons that we as Christians may not be as effective of a witness that we should be is because we are too much of this world. The lost looks at us and can't tell the difference between our lives and theirs. Sadly our speech is often as vulgar as theirs. Our entertainment is often the same. The places we go and the music we listen too is often no different. Then we wonder why our witness is not more effective.
Not all movies, music, magazines and tv programs are off limits but a great many are so use the Philippians 4:8 approach when trying to decide what is God honoring and what isn't. Paul says, "

⁸ Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things."
Remember we are in the world but not of it. Romans 12:2.
