Ever heard of the saying “You are what you eat?” Well, the same is true with your thoughts; you become what you think. Fixing our thoughts on the positive allows our outlook to be positive, even if we are surrounded by negativity. Paul is trying to show us that we can rise above behaviors we detest. It all starts with thoughts, which lead to actions, and eventually become habits.
And now, dear brothers and sisters, one final thing. Fix your thoughts on what is true, and honorable, and right, and pure, and lovely, and admirable. Think about things that are excellent and worthy of praise.
~ Philippians 4:8 [NLT]
