That’s what witnesses have to do every day.
why?
First they are told they are imperfect , that they can never fight the desires of the flesh.
Then they are told that they must follow the example of Jesus who is perfect.
So they are “encouraged to engage in the ministry work attend all meetings do bible study amongst other tasks.
If they fail to do so the magazines and talks make clear they are spiritually weak. So they must try harder .
To progress you must do more on the ministry go to more meetings and do more study.
Yet at what point does imperfection kick in and rule out doing more of these things.
If you fail to go on the ministry on a Saturday morning even though you are not in work are you spiritually weak or imperfect?
As a witness you never can know.
You are helped to asses your own abilities with the help of the magazines and talks. These will never say if you miss a meeting or don’t study don't worry your are imperfect but will highlight spiritual weakness and encourage you to do more.
But what is imperfection. If it is imperfection that stopped you going on the ministry then you are not spiritually week ad able to do more just imperfect and there is nothing you could do about it. But you are always told you can do more so you always have a mountain to climb.
A witness can never decide he is doing all he can because the magazines and talks will always tell him to do more.
Witnesses are left with an impossible task.
