No, that is not what I mean, SC.
The Bible does tell us to separate ourselves from the world.
What that means is that we are not to be a part of certain things in the world that are sinful.
Yes, we have to go out in it; grocery shopping, jobs, school, and so on,
But we do not have to participate in sinful activies with sinners.
Other than teaching/talking the Gospel we are suppose to separate ourselves.
