It shows how you have to "earn" life according to the WTS.
Remember when Peter had to have 2 visions to get him to go and see the Gentile centurion Cornelius. Even then he would not baptize him until holy spirit fell upon him and his family. It shows that it is God who determines who is acceptable not men. Who determines if they have "taken the steps that would identify them as part of God's household."
Try and find a scripture were the early Christians called each other "Brother Timothy" or "Brother James."

km 4/96 p. 7 Question Box ***On the other hand, interested persons who have only recently begun to attend our meetings have not yet taken the steps that would identify them as part of God?s household. These individuals would not be addressed as "Brother" or "Sister," since the spiritual relationship of God?s family does not exist in their case. So during the meetings, we would address them more formally, using an appropriate title such as "Mr." with their last name.
Notice how the WTS sidesteps the question but gudgingly admits there is no example in the NT.

Why do the witnesses of Jehovah address each other as "Brother" and "Sister"? I have never found any Scriptural authority for it. Jesus always addressed his disciples as "Peter," "John," and so forth, but never as "Brother Peter" and "Brother John."?E. J., United States.There are valid reasons for dedicated Christian believers to refer to one another as "Brother" and "Sister." It is true that, with few exceptions, these terms when used in the Gospels and in the book of Acts refer to flesh-and-blood relatives. However, Jesus did use the expression "brother" in a general sense for fellow believers when he said: "Look! My mother and my brothers! For whoever does the will of my Father who is in heaven, the same is my brother." Also, "If your brother commits a sin, go lay bare his fault between you and him alone. If he listens to you, you have gained your brother."?Matt. 12:49, 50; 18:15.
The apostles and disciples of Jesus used the term "brother" in an even more direct sense. And so we repeatedly find such expressions as these occurring throughout their writings: "Quit mixing in company with anyone called a brother that is a fornicator," said Paul. Ananias, the faithful disciple, referred to the persecutor Saul, who had repented, as "Saul, brother." Later, Paul himself spoke of "Sosthenes our brother," "Apollos our brother," "Titus my brother," and "our brother Timothy." So also Peter referred to Paul as "our beloved brother Paul." And in Acts 21:20 we read: "They said to him: ?You behold, brother, how many thousands of believers there are among the Jews.?" Surely in view of all these examples there can be no valid objection to it when Christians refer to fellow believers as "Brother" and "Sister."?1 Cor. 5:11; Acts 9:17; 1 Cor. 1:1; 16:12; 2 Cor. 2:13; Heb. 13:23; 2 Pet. 3:15.
The use of a family name as well as a given name, which was not the practice in the first century, has also made it advantageous to use the expression "Brother" with the family name as is now done. It helps avoid both the extreme of undue familiarity and that of undue reserve. To address an adult by his given name today indicates a familiarity that may not always be fitting, especially not on the part of youth toward adults or on the part of strangers to one another. On the other hand, to use the formal term "Mister" would savor of a lack of friendliness, a reserve that does not prevail among the members of the dedicated Christian community. Therefore "Brother" and "Sister" appear to be the logical as well as Scriptural designations to use, since dedicated Christians view one another as members of a spiritual or religious family.
