1 Corinthians 6:15

Know ye not that your bodies are the members of Christ? shall I then take the members of Christ, and make them the members of an harlot? God forbid (KJV)

Then: Corinthians took a hard hit with this "Don't you know?" question. The thing attacked their belief that continuing their daily social practices had no affect on anyone's commitment to Christ. They heard the word "members"and knew it specifically meant the various parts of the body (Baker, p. 91). Paul slams them with the thought that their actions connected Christ to prostitutes. No one could imagine the lamb of God like that. God forbid (Baker, p. 94).

Now: Sex is everywhere - Television, newspapers, books, magazines, radio, internet. It cannot be avoided. Entice or shock, the advertisers aren't particular. The point is to attract attention and then sales. Even those with a shred of decency, usually hoping to protect children, are under attack by the politically-correct. Secular theologians denying Christianity and worshiping elsewhere march willy-nilly through the land. Christians' eternal commitments need the strengthen of absolute convictions in order to avoid today's harlotry.
