1 Peter 3 teaches some principles regarding right Christian living. Our lives witness to unbelievers more than our words, so be careful that our behavior is pure and godly. We should value the attitude and inner spirit of a person more than their outward appearance, since only these are valued in God's eyes. Behave rightly toward others with honor and respect and understanding, since otherwise "your prayers will not be heard" (3:12 also). Peter lists five aspects that should characterize believers 1) one mind (pursuing the same goals), 2) sympathy (responsive to others) , 3) love ( treating each other as family), 4) tenderness ( caring and sensitive), 5) humility ( encourage and rejoice together). Lastly, Peter reminds us again that we may suffer for doing what is right, but God will reward us for it. He says "don't be afraid" then, and "don't worry", since we can trust in our "Shepherd, the Guardian of your souls".
