9 not giving back evil for evil, or railing for railing, and on the contrary, blessing, having known that to this ye were called, that a blessing ye may inherit; 10 for 'he who is willing to love life, and to see good days, let him guard his tongue from evil, and his lips—not to speak guile; 11 let him turn aside from evil, and do good, let him seek peace and pursue it; 12 because the eyes of the Lord 'are' upon the righteous, and His ears—to their supplication, and the face of the Lord 'is' upon those doing evil;'
Matthew Henry's Commentary on 1 Peter 3:9-12
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.
