8 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. 9 Don't repay evil for evil. Don't retaliate with insults when people insult you. Instead, pay them back with a blessing. That is what God has called you to do, and he will grant you his blessing.
Matthew Henry's Commentary on 1 Peter 3:8-9
Commentary on 1 Peter 3:8-13
(Read 1 Peter 3:8-13)
Though Christians cannot always be exactly of the same mind, yet they should have compassion one of another, and love as brethren. If any man desires to live comfortably on earth, or to possess eternal life in heaven, he must bridle his tongue from wicked, abusive, or deceitful words. He must forsake and keep far from evil actions, do all the good he can, and seek peace with all men. For God, all-wise and every where present, watches over the righteous, and takes care of them. None could or should harm those who copied the example of Christ, who is perfect goodness, and did good to others as his followers.
