One sense in which we are “brothers” is that all of us have descended from Adam. (Acts 17:26) But there is more. Jesus explained that his disciples were brothers and sisters because they recognized Jehovah as their heavenly Father. (Matt. 12:50) In addition, they had become members of one large spiritual family, united by love and faith. Thus in their letters, the apostles often referred to fellow disciples as ‘brothers and sisters.’ (Rom. 1:13;1 Pet. 2:17; 1 John 3:13) After making it clear that we should view one another as brothers and sisters, Jesus stressed the need for humility. (Matt. 23:11, 12) Undue pride among his apostles had led to some disunity. And pride of race could also have been a problem. Did the Jews have reason to be proud because they were descendants of Abraham? Many Jews had that deep-seated conviction. But John the Baptist told them: “God is able to raise up children for Abraham from these stones.”​—Luke 3:8. w18.06 9-10 ¶8-9

Ask yourself: ‘Is my complete allegiance to Jehovah evident to others? Do I look for opportunities to identify myself as one of Jehovah’s Witnesses?’ Jehovah would be deeply saddened if after he has selected us as his people, we were to hesitate to let others know that we belong to him. (Ps. 119:46; Mark 8:38) Sad to say, some individuals have blurred the distinction between their serving God and their not serving him by imitating “the spirit of the world.” (1 Cor. 2:12) That is a spirit that caters to ‘the desires of one’s flesh.’ (Eph. 2:3) For example, despite all the counsel that has been given on the subject, some still prefer styles of dress and grooming that are immodest. They wear tight-fitting and revealing clothing, even to Christian gatherings. Or they have adopted extreme haircuts and hairdos. (1 Tim. 2:9, 10) As a result, when they are in a crowd, it may be difficult to tell who belongs to Jehovah and who is “a friend of the world.”​—Jas. 4:4. w18.07 24-25 ¶11-12

Jehovah places no significance on racial, ethnic, national, tribal, or linguistic differences. Any man or woman who fears God and does what is right is acceptable to him. (Gal. 3:26-28; Rev. 7:9, 10) No doubt, you acknowledge that this is true. But what if you have grown up in a land or in a home filled with prejudice? While you might see yourself as being impartial, deep inside, prejudice may linger. Even Peter, who had the privilege of revealing Jehovah’s impartiality, later manifested prejudice. (Gal. 2:11-14) How can we stop judging by the outward appearance? We need to examine ourselves carefully in the light of God’s Word to see if we are holding on to any prejudiced thoughts or feelings. (Ps. 119:105) We might also need loving help from others who may see prejudiced attitudes in us, even if we cannot see them in ourselves. (Gal. 2:11, 14) It could be that these attitudes are so ingrained in us that we are not conscious of them. w18.08 9 ¶5-6

It can be a challenge to maintain a generous spirit when we are surrounded by people who put their own interests ahead of those of others. However, Jesus stated that the two greatest commandments are to love Jehovah with our whole heart, soul, mind, and strength and to love our neighbor as ourselves. (Mark 12:28-31) Those who love Jehovah imitate him. Jehovah gives to others, and so does Jesus. And they recommend that we do the same, for it will make us truly happy. If we strive to manifest this generous spirit in our dealings with both God and neighbor, we will bring honor to Jehovah and benefit ourselves and others. No doubt you are already striving to give of yourself to help others, especially fellow believers. (Gal. 6:10) If you continue to do so, you will surely be loved and appreciated, and you will be happy as a result. w18.08 22 ¶19-20
