What we put into our minds determines what comes out in our words and actions. Paul tells us to program our minds with thoughts that are true, noble, right, pure, lovely, admirable, excellent, and praiseworthy. Do you have problems with impure thoughts and daydreams? Examine what you are putting into your mind through television, books, conversations, movies, and magazines. Replace harmful input with wholesome material. Above all, read God’s Word and pray. Ask God to help you focus your mind on what is good and pure. It takes practice, but it can be done.

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
