Quit You Like Men

In this verse Paul (who is politically gender insensitive by today’s standards) is telling the Corinthian men to … act like men of God, God’s men.  How do we define what it is to be a man of God?  What is our mind suppose to envision?  Wonder what examples Paul would have used when reenforcing his call for men to be God’s men?  

Perhaps … Abraham, Moses, Gideon, Joshua?
