It used to be that individuals were arrested for public drunkenness. That’s very rare anymore. Rather we seem to find great amusement and are brought to laughter at the sight (and sound) of such today. It used to be that sex outside of 
marriage (i.e., adultery, marriage) was frowned upon and looked at with public shame. Again, that’s very rare anymore. Rather it’s almost “the expected thing” today, and we are regularly entertained by such in movies and television.
What has happened? Paul’s words–almost 2,000 years old–fit our modern culture perfectly: “…having their understanding darkened, being alienated from the life of God, because of the ignorance that is in them, because of the blindness of their heart; who, being past feeling, have given themselves over to lewdness, to work all uncleanness with greediness” (Eph. 4:18-19). If you didn’t know those words were penned 1,950 years ago, you’d think it was a commentary on modern America. Truly, “Fools mock at sin” (Prov. 14:9). So, what about us? What about you? Will we strive to “be separate,” “perfecting holiness in the fear of God” (2 Cor. 6:17-7:1)?
