Worldliness is not just doing the things that the world does, but it's also wishing that you could do the things of the world. One of its characteristics is mental slavery to illegitimate pleasures. Playing mental games with sin will lead you to active involvement with sin. Playing mental games with things that are forbidden is also worldliness. Our behavior as Christians should be good.
Worldliness twists values by rearranging their price tags.
We should be people who are involved in the community in the proper way. Christians offer a shared table, but not a shared bed. We are passing our days on earth, but are citizens of heaven. We obey the appointed laws, but go beyond the laws in their own personal conduct. We love every one, but are persecuted by many.
