If Ephesians 5:12 Had Never Been Written

Watching the flurry of posts recently on Driscoll's new book on marriage, I rather enjoyed this quote by Carl Trueman on the Ref21 blog-

I have often in the past stood with those who laughed at what we regarded as the ignorant, unsophisticated taboos of the older generation. But now I worry about the ease with which the rising generation talks explicitly of 'the fruitless deeds of darkness' in the name of cultural engagement, fear of being thought passé or simply a desire to slough off the legalisms of their fathers in the faith. You can, after all, get to heaven without ever having seen an R-Rated art house movie or having enjoyed a spectacular love life.

Here's a question: would it make any difference to you, any difference at all to the way you talk, to what you watch, to the wayyou 'engage culture', if Eph. 5:12 had never been written?

Would it?
