8 Finally, all of you, have unity of spirit, sympathy, love for one another, a tender heart, and a humble mind. 9 Do not repay evil for evil or abuse for abuse; but, on the contrary, repay with a blessing. It is for this that you were called-that you might inherit a blessing. 10 For "Those who desire life and desire to see good days, let them keep their tongues from evil and their lips from speaking deceit; 11 let them turn away from evil and do good; let them seek peace and pursue it. 12 For the eyes of the Lord are on the righteous, and his ears are open to their prayer. But the face of the Lord is against those who do evil."

(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.
