Liberals, especially those with graduate degrees in any of the squishy sciences, are notorious for their wrongheaded ideas. Cohabitation should be tried as a "trial run" for marriage. Spanking is bad because it teaches children that violence is the solution to problems. Little boys shouldn't play with guns because it will turn them into violent criminals.
Fortunately, our wisdom comes from Scripture and not from some poor soul with a doctorate in women's studies. In his excellent book Future Men, Douglas Wilson remarks that his two-year-old grandson is captivated by the story of St. George and the dragon. Wilson writes:
Men who follow Jesus Christ, the dragon-slayer, must themselves become lesser dragon-slayers. And this is why it is absolutely essential for boys to play with wooden swords and plastic guns. Boys have a deep need to have something to defend, something to represent in battle. And to beat the spears into pruning hooks prematurely, before the war is over, will leave you fighting the dragon with a pruning hook.
The Christian faith is in no way pacifistic. The peace that will be ushered in by our great Prince will be a peace purchased with blood. As our Lord sacrificed Himself in this war, so must His followers learn to do.
Boys must learn that they are growing up to fight in a great war, and they must consequently learn, as boys, to be strong, sacrificial, courageous, and good.
