Philippians 4:8-9

8Now my friends, I want to say this to you. Fill your minds with thoughts about good things. Think about things that are true, clean, right and lovely. Always think about things which people know are very good.

9Remember what I have taught you. Remember the message that you heard from me. Remember what you saw when I lived among you. You also must do those same things. God is the one who gives us peace in our minds. He will be with you.
