Battle of the mind

Nothing helps me to battle impure thoughts better than this verse, "Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy-meditate on these things." Philippians 4:8 I love this verse because when I am thinking about things I shouldn't be I go, "Oh, that's not lovely. That's not pure! That's not praiseworthy!" It helps me to shut damaging thoughts down.
