I have defended Jesus' deity several times on this forum. But as you have discovered, there's not much point debating it with someone who denies the authority of Scripture, let alone Jesus' Godhood. LITS is indeed free to believe his version of the gospel, but there is no question that his is 'another gospel'. God does not make personal revelations to ppl that confirm their own predisposition to cherry-pick the bits with which they agree, and destroy the authority of His own Word. That amounts to a self-authenticating tautology, and is worthless in terms of validation of one's personal beliefs.
Unless LITS is willing and able to provide us with a comprehensive list of all the Scriptures with which he does agree (which no doubt will be radically different from the next person who is also inclined to cherry-pick his favourite bits), it is simply not possible to engage with him on any meaningful level.
I applaud you for trying though Rainy, even if the outcome was predictable.
