I was always, and still am, a "true believer" in the Bible.
I was only a true believer" in the WTC, however, until I was 13 or so. Then I left, got DFd, only to come back in as a beliver in the Bible, but increasingly grew at odds with how the WTC consistently and continuously expanded their dogma "outside the things written".
From that time onward, I attempted to get them to realize this, and stop their apostate practices, to no avail, obviously.
So, I feel now, as I did then, that the Bible is "the Truth", just as Jesus Christ stated in John 17:17.
