As far as I know, Brett and Kate McKay are not Christians. Nevertheless, they grasp the significance of a serious social problem: the lack of maturity among young (and sometimes older) men. They’ve published a pretty thoughtful essay on the topic at The Art of Manliness. It’s well worth a read.
When people say they don’t want to embrace adulthood, what they really mean is that they don’t want to be a grownup themselves, but they want to live in a world where everyone else is. They want competent, effective politicians to represent them; they want their journalists and doctors to be smart and level-headed with a comforting mantle of gravitas; they want their children’s teachers to be dedicated and on-the-ball; they want customer service to be friendly and efficient; they want police officers to be honest and fair. They want the world to be stable, predictable…so they can afford to be erratic and irresponsible. They want to be kids, but live in an adult world, where grownups are at the ready to take care of their every need.
