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: 11 And let him be turned from evil and do good; searching for peace and going after it with all his heart. 12 For the eyes of the Lord are on the upright, and his ears are open to their prayers: but the face of the Lord is against those who do evil.
Matthew Henry's Commentary on 1 Peter 3:10-12
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.
