15 If an upset person does not work at controlling his emotions and making peace with his brother, a grudge could develop. There have been cases when a Witness asked not to be assigned to a certain Congregation Book Study because he did "not care for" some Christian or family attending there. How sad! The Bible says it would be a defeat for Christians to take one another to worldly courts, but would it not be equally a defeat if we avoided a brother over a past slight to us or to some relative? Do our emotions reveal that we put blood relationships ahead of peace with our brothers and sisters? Do we say that we would be willing to die for our sister, but our emotions so move us that we hardly speak with her now? (Compare John 15:13.) God tells us pointedly: "Return evil for evil to no one. . . . If possible, as far as it depends upon you, be peaceable with all men. Do not avenge yourselves, beloved, but yield place to the wrath."—Romans 12:17-19; 1 Corinthians 6:7.I always wanted to go to the cool book study !
