A lot is expected from Jehovah's Witnesses.
It's not easy to know when they've done enough for Jehovah. Perhaps they could have done just a little more and didn't. Perhaps they could have helped God saved one more life but failed to do so.
Jehovah's Wtinesses wonder if God will hold them accountable if they don't work hard enough and give everything they can possibly give.
The uncertainty of their salvation is troubling.
The Watchtower says this about eternal life, ' At congregation meetings, assemblies, and conventions arranged by “the faithful and discreet slave,” you obtained knowledge that will lead to everlasting life on a paradise earth without pain and suffering.' Watchtower July 15, 2009, Article: 'Accept Gratefully - Give Wholeheartedly'. 
The Watchtower says this, 'One day, death will be no more. (Rev. 21:4) While we await the realization of that grand promise, may Jehovah find us spotless, unblemished, and completely separate from this wicked world and its God-dishonoring practices.—2 Pet. 3:14.' Watchtower Feb 15, 2009, Article: 'Christian Funerals—Dignified, Modest, and Pleasing to God.'
The 2010 Elder's manual, Shepherd the Flock of God, outlines many of the rules Jehovah's Witnesses must follow in order to please Jehovah and 'His organization'. Other rules are mentioned the organization's literature.
Since Jehovah's Witnesses don't have access to the rule book for Elders, many disagree that the organization has any rules. They believe they are following the Bible, Jehovah, Jesus, and their conscience. However the Elders know the rules and it's their job to act decisively when anyone steps out of line.
The Watchtower says, 'By word or action, may we never challenge the channel of communication that Jehovah is using today. ... we should cherish our privilege to cooperate with the slave class.' Watchtower Nov 15, 2009, article, 'Treasure Your Place in the Congregation', par 5. In the same article, Jehovah's Witnesses are warned about disobedience, disrespect, and a spirit of independence. JW's are expected to be obedient and submissive to those taking the lead.
The organization says this, 'For the great majority of those who choose to do God’s will, the prize worth working for is eternal life in a new world of God’s making.' March 15, 2009, Article: 'Keep Your Eyes on the Prize'
For JW's, eternal life is the illusive carrot that's ever so close, but never within reach. Just take one more step forward. Do this over and over again. You'll make it if you don't tire out. Never stop. Eternal life is the 'prize' worth working for.
Is that what the Bible says? Is it true that eternal life is a 'prize' we need to work for?
Jehovah's Witnesses are not aware they can have a permanent place in God's kingdom without working for the organization. John 8:34-36;
The Bible says eternal life is 'inherited', - not earned. In other words eternal life is free. The truth is simple.
The Bible says this. "Teacher," he asked, "what must I do to inherit eternal life?" "What is written in the Law?" he replied. "How do you read it?" He answered: "'Love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind'; and, 'Love your neighbor as yourself.'" "You have answered correctly," Jesus replied. "Do this and you will live." Luke 10:25-28
