Philippians 4:8-9

8Finally, believers, whatever is true, whatever is honorable and worthy of respect, whatever is right and confirmed by God’s word, whatever is pure and wholesome, whatever is lovely and brings peace, whatever is admirable and of good repute; if there is any excellence, if there is anything worthy of praise, think continually on these things [center your mind on them, and implant them in your heart].

9The things which you have learned and received and heard and seen in me, practice these things [in daily life], and the God [who is the source] of peace and well-being will be with you.
