For a witness of jehovah it is important to ask what means "BEING IN THE TRUTH" actually.
when jesus asked "what is truth" this could be understood as hint that human awarness is limited. Human awareness of truth....the new testament teaches that faith and revelation of god himself overcome the limitation and that the way to this truth is a way of relationship between man and god.
Nobody disposes of this truth absolutely, it can be made accessible time and again anew along a way, as pope Francis wrote in La Republicca, 9/12/13
„You ask me further if it is an error or or a sin to believe that an absolut truth does not exist. First I would say that also for a beliefer we would not speak of an "absolut" truth - for a christian the truth is the Love of God to us in Jesus Christ, thus a relationship! and each of us goes from own impulse when he adopts the truth and expresses is: dependent from his culture, history and situation ..... This does not mean that truth is subjective or changeable in contrary. But it offers itself to us as a way and as life. Did not jesus himself say: I am the way, the truth and the life? (translation mine)
Being in the truth - What do JW understand ?
a) being in the state of having all correct understandings of any doctrinal matter ..... certainly not
b) always telling the truth except in cases where Jehovahs name is in danger ... certainly not
c) living in harmony with JehovaH and his organisation, being in the way in the protected group .... more probably
d) accepting the gospel as "truth" ...less? probably
e) jesus is the truth and all words that he said? probably
...
in hebrew bile the word "truth" means something like "Amen"..... reliabilty ~ loyality and the gamut of reality
If this was seen as the key christian teaching than authority of the GB would not be so important but the relationsship with god.
Summary:
The christian "truth" is not
- a speculation about philosophical absolut truth
- nor an organisational value systems/ legal system/doctrine
- nor everlasting new flashes of light or explanations/prophesies from a channel
but simply the relationship of love between God and men in Jesus.
