9 Not giving back evil for evil, or curse for curse, but in place of cursing, blessing; because this is the purpose of God for you that you may have a heritage of blessing. 10 For it is said, Let the man who has a love of life, desiring to see good days, keep his tongue from evil and his lips from words of deceit:
Matthew Henry's Commentary on 1 Peter 3:9-10
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.
