Here's what I want to know:
JWs claim that the tetragrammaton (YHWH) was removed 237 times from the original writings of the New Testament.
If the Bible is trustworthy, and God saw to it that the Bible came to us virtually unchanged after several thousand years of hand-copying, in many instances (esp. the New Testament) by non-professional scribes very prone to error, why couldn't he see to it that his name was preserved those 237 times?
If "the name" is that hugely important, wouldn't that be the one thing that he wouldn't let get corrupted out of the text?
Either the text is reliable, in which case the use of YHWH in the NT is totally unsupported (as zero Greek texts contain it), or the text is unreliable, in which case who cares what it says now - it must be different than what was originally written.
You can't have it both ways.
