Watching over the church of God is a good thing. And it is a good thing for a man to aspire to it. But not just anyone can be an overseer. The primary qualifications must be a certain type of heart or character. This heart-character will be revealed by certain types of activity. Scripture tells us in several places that words and actions reveal what is in the heart.
God takes these men and set them to watch over His family. God also gives them to be models. He encourages His children to imitate these men. So, God wants all His children to grow to have this heart, this character and to demonstrate this activity. This description should describe anyone who follows Jesus.
