I used to be like that; enjoying arguing the doctrines.
But I discovered something. Witnesses will say that Christendom lies in that they teach the trinity and hellfire, etc.
But that is not a lie, it is that they just interpret the Bible differently than JWs do.
I've never seen God so I don't know if he is a trinity. Same goes for Greg Stafford, Walter Martin, James White, etc.
I've never been to heaven or hell so I don't know what goes on there. Same for the above named people.
It's up to God to clarify matters, not our arguing.
