I know a guy in his late 30’s that still lives at home with his mom. He does not have a job though he is physically and mentally capable, he eats her food, lives in her house, and does nothing but play video games. He is what is called a Man-Child. Paul does not want us to be spiritual man-children or woman-children. He wants us to mature into spiritual adulthood so that we can join the mission of God and build up the Church.
