In the 1970s, there was a popular book called The Peter Principle by Laurence Peter. The premise of the book was that successful people often receive promotions until they’re finally promoted to a level of incompetence. 

The most common application of this principle is in sales. After many great salespeople have success, they often assume their next step is to become a sales manager.  

However, some great salespeople are poor managers.  

Philippians 2:3 teaches, “In humility value others above yourselves, not looking to your own interests but each of you to the interests of the others.”  

To look out for the interests of others, sometimes you’ll need to refrain from promoting some to a place of incompetence, ultimately harming them and your team. Instead, encourage and reward their God-given gifts.
