I have recently become convinced that evangelical American Christians do essentially two things pretty well. They keep their kids from swearing, and they keep them from having sex before marriage, or at least they clearly express their displeasure with those two specific sins. And I believe that they are sins (for the most part). For the first sin, as Ephesians 5 says, "Nor should their be obscenity, foolish talk or coarse joking, which are out of place, but rather Thanksgiving." And the latter should be clear from many verses about purity. So I'm not saying that Christians are off base by discouraging these sins in their children. I just wish that they would treat other sins with the same tenacity that they do these two.
Imagine if a parent would wash their child's mouth out with soap for gossiping? Or for using coarse language that's not included in our society's list of "swear words"? Or if they would give their children lectures on the dangers of coveting? Or jealousy? What a better church we would have! What a more Christlike body of believers we would have! If only Christians could harness their cursin' and sex fighting zeal to every area of their children's lives.
