Philippians 4:8 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. 

1 Peter 1:15-16 But now you must be holy in everything you do, just as God who chose you is holy. For the scriptures say, “You must be holy because I am holy.”
