Pistoff, Mizpah answers, albeit unintentionally, your query as to where does Jesus command his followers to form congregations. Jesus gave a revelation to John about 7 congregations in John's time, their faults and strengths. Jesus therefore clearly approves of a congregational arrangement, and the fact that he poured the holy spirit out, the 'helper' onto those in the first century congregation arrangements is also evidence of this (that is not to though that say he approves of a huge multi-billion dollar publishing house that has become like an idol and more or less replaced the role of Jesus.)
Yes, there is a big problem that every religion claims to have God's holy spirit, but that is what THEY say. That doesn't mean that God ISN'T possibly using one religion, faults and all. Satan keeps transforming himself into an angel of light however, so it is not surprise that all of them claim to be a path to God. The trick is to sift the rubbish from the good stuff, and elimate what are clearly counterfeits. Now I'm not asserting that Jehovah's Witnesses are not full of counterfeit christians, because they most surely are riddled with them, even to the highest level, but the fact they they have boldly exposed so many Babylonish pagan myths mimicking as christian teachings as false and unscriptural separates them a lot from other churches in Christendom in my mind.
Sorry Badolpuddytat (cute name) but didn't Jesus say that 'all things are possible with God'!, From our imperfect human standpoint it may seem an impossibility that a true religion could exist, but if God so wanted to he truly could. There would still be imperfect humans in that religion, but doctrinally and in it's interpretations of prophecy etc, it could be perfect if God so chose to reveal. Not that that means he is necessarily doing so right now mind you.
