[Be] of the same mind one toward another. Mind not high things, but condescend to men of low estate. Be not wise in your own conceits.
Note 10 at Ro 12:16: This is not saying that Christians should never occupy prominent positions. If that were true, then Paul would not have needed to admonish these people to be willing to associate with those of low estate. They wouldn't have any other choice.
Many Bible people were people of renown, even among the unbelievers [examples: Abraham, Isaac, Joseph, David, Solomon, Paul (Ac 28:7), and John (Joh 18:15)]. Paul was just saying that we shouldn't seek out prestigious people and snub those whom the world doesn't consider important. God doesn't evaluate people the way that the world does. Those who are greatest in His kingdom are the greatest servants.
We will miss some of the most beautiful people who could bless our lives if we judge people by the world's standards. We also run the risk of destroying our faith when we seek the honor that comes from man (see note 22 at Joh 5:44).
