Narkissos,
We may never know what Truth is, unless God, if He exists, let us know, maybe one day. For the time being Jesus' words assure us that there is a truth but He indeed doesn't tell us much about it. If I ever know anything, one of the best things I know is that, like pudding, I proved the veracity of at least some aspects of the JWs' teachings in the most practical way since I stopped smoking during the time I was *studying* with them, 30 years ago. I know all their shortcomings and yet I'm grateful to their truth for having set me free from tobacco addiction and being still here to bear witness to it. (between you and me : you know that the last volume issued next thursday with Le Monde is HUME, the empiricist, let's not miss it !)
