Spend five minutes with my boys and you’ll quickly discover, anything they do turns into a conquest of some evil force, with some kind of weaponry, to protect some other helpless entity—even if it all began as a match-making game of flipping cards. The cards become guns, the straw hat becomes a Texas Ranger’s mantle, and the donkey (no mere innocent bystander when three-footers are around) is obviously the notorious Evil Doctor Donkenator.
Doug Wilson has some helpful insight into why boys always do this:
Men also have a deep desire to deliver or save. The great example of a savior is, of course, the Lord Jesus Christ… 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…
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.(15-16).
