Q: Is Myspace sinful?

A: No!

Mark 7:14-16 "Then Jesus called to the crowd to come and hear. “All of you listen,” he said, “and try to understand. It’s not what goes into your body that defiles you; you are defiled by what comes from your heart."

I am amazed at what some Christians get up in arms about; Harry Potter, Drinking, The DaVinci Code, Myspace, Gays, great music by great artists who aren't professing Christianity in each song they sing...
Myspace is what it is... a place to connect, engage in converstations, find friends, sell, promote, create community, reach people, meet people, etc. Yes you can see bad stuff on Myspace, hello, it's the internet! There are many places on the internet 50,000 times worse then Myspace! And to that I say... don't go there! Yes, Myspace has some stuff you have to be smart about... to that I say... BE SMART!
I personally have a software protection program that notifies 3 accountability partners what I have looked at on the internet and that includes Myspace profiles.
We (our church) have actually reached people through our Myspace page. This was the whole reason we even created a Myspace page. This is because we believe you CAN NOT reach the world by hiding in your little Christian Cacoon with other Christians.
There are many sites a lot like Myspace; i.e. Facebook, Bebobebo, hi5, flixter, friendster, yuwie, xanga and I am sure there are 100 others. I have heard Facebook is much cleaner (Rated PG) which would be a better choice for a teenager I would think.
