The Apostle Paul challenges us to choose what we let our minds focus on:
Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.
He’s directing us to let our minds focus on these things.
