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.

13. who … will harm you—This fearless confidence in God's protection from harm, Christ, the Head, in His sufferings realized; so His members.

if ye be—Greek, "if ye have become."

followers—The oldest manuscripts read "emulous," "zealous of" (Tit 2:14).

good—The contrast in Greek is, "Who will do you evil, if ye be zealous of good?"
