Those who simply refuse to hear or accept the message of the good news are not acceptable companions (uw 44-5) - Talk Outline #14, p2 - A Clean People Honors Jehovah
The talk outline says it very straight forward and without any BS: If you don't believe what the WTS teaches then you are not acceptable to JWs and are to be rejected. Here is what the reference in the United In Worship (uw) book says: Where the Problems Begin 13 Stop and think about where those problems often begin. The Bible explains: "Each one is tried by being drawn out and enticed by his own desire. Then the desire, when it has become fertile, gives birth to sin; in turn, sin, when it has been accomplished, brings forth death." (Jas. 1:14, 15) But how do those desires get stirred up? By what goes into the mind, and often this is as a result of association with people who do not apply Bible principles. Of course, we all know that we should avoid "bad associations." But the question is, Which associations are bad? How does Jehovah view the matter? Reasoning on the following questions and scriptures should help us to arrive at proper conclusions.
14 Immediately ahead of us lies God’s New Order. By means of His Kingdom mankind will be freed of the enslaving influence of Satan and his entire wicked system of things. Gradually all the effects of sin will be removed from mankind. Eternal life in Paradise will lie before them. Freedom that is in full harmony with "the spirit of Jehovah" will eventually be enjoyed by all creation. (2 Cor. 3:17) Would it make sense to risk losing all of that because of treating lightly the counsel of God’s Word now? By the way in which we exercise our Christian freedom today may we all show clearly that what we really want is "the glorious freedom of the children of God."—Rom. 8:21.
