1. Humble
2. Honest
3. Hungry
Lets consider why JWs search for these qualities or advertise that they are necessary.
Humble - Someone who is uneducated, poor, non-critical, thinks they are not worthy and longs for help getting truths. Ready to be exploited.
Honest - Read this as someone ready to agree with the GB and believe whatever they are told. Someone ready to honestly agree with all they the spiritual food they are shoveled. Someone ready to acknowledge they don't know the answers and must be told. Ready to be exploited.
Hungry - Well of course they need to be hungrily searching for more than they have. Paradise appeals to those people. Hunger keeps you at meetings and in service. Hunger keeps you going looking for that elusive free meal reward.
Sadly it all makes sense now.
