What Makes A Man Of God?

If you haven’t been living under a rock for the last few months, you have no doubt heard of Saint Biden. You might know him as our new president. But, since he is such a down to earth kind of guy, you can just call him Joe.
 
The media has recreated Joe as a church-going man of God. I’m not here to build him up or tear him down with this post, so I’ll just leave you to draw your own conclusions. However, it does raise the question, “What makes a man of God?” Obviously, all the same questions could be asked about women, I’m just using “man” in the general sense.
 
Is a man of God someone who is a “good” person?
Is a man of God someone who goes to church regularly?
Is a man of God someone who simply believes in God’s existence?
Is a man of God someone who believes in the Bible?
Is a man of God someone who prays to the “big guy in the sky?”
Is a man of God someone who helps others?
Is a man of God someone who obeys the things God says in the Bible?
Is a man of God someone who advocates for things against the Bible?
Is a man of God someone who confesses his sin and repents?
Is a man of God someone who does his best, dismisses his sin, and goes on with his day?
 
What is a man of God according to you? Does your opinion even matter? Does your opinion hold more weight than mine or the dude down the street?
Should what God says about what makes a man of God count for more than all of us?
