It all makes logical sense though—JW interpretation of the Bible—to the point of being mentally and emotionally convinced to the point of dying for your beliefs such as blood and political neutrality.
You can be sincere AND sincerely wrong at the same time. Fortunately, people won't be judged on whether or not they are sincere or if they died for their beliefs. They will be judged after they die on whether or not they have broken any of the 10 commandments.
To deal with this LITERAL judgement, Jesus LITERALLY substituted for the sin that individuals carry: "he became sin for us". and codified this "forgiveness of sins" into a contract at MT. 26: 27-28.... the same contract JW's disrespect and reject every memorial.
it is appointed unto man once to die and then to face judgement. - Heb. 9; 27
There is nothing symbolic about any of this stuff. Symbolism is just another word for rejecting the words of God.
JW's on the trial before God: "I'm sorry your Honor, I sincerely thought your judgement was only symbolic. I was told that my sins would be wiped away and I would be given a clean slate after I die.".
God: "Why didn't you believe me over them? Didn't you know they had a 100% prophecy failure rate"?
Get off the crazy train and read the bible literally, unless it tells you that something is a symbol or means something else. If it doesn't say that, just take God at his word.
