Philippians 4:8-9 — Finally, brothers, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think on these things. Whatever you have learned or received or heard from me, or seen in me, put it into practice. And the God of peace will be with you.
1 Thessalonians 5:11 — Therefore encourage one another and build each other up, just as in fact you are doing
