1 Peter 3:8-9, NLT: All Christians – Finally, all of you should be of one mind. Sympathize with each other. Love each other as brothers and sisters. Be tenderhearted, and keep a humble attitude.

1 Peter 3:10-12, NLT: For the Scriptures say, “If you want to enjoy life and see many happy days, keep your tongue from speaking evil and your lips from telling lies. Turn away from evil and do good. Search for peace, and work to maintain it. The eyes of the Lord watch over those who do right, and his ears are open to their prayers. But the Lord turns his face against those who do evil.”
