Unless it tells you otherwise, ALL of the bible is literal . Symbolism supports an elite class. Try reading the bible without all the symbolism and it will really open things up and reveal the errors.
For instance, there will literally be 144K male Jewish virgins that will evangelize the world during the Great Tribulation. Their message will be the good news of god's kingdom that is about to manifest.
This explains why Christians are preaching the "ministry of reconciliation" while JW's are preaching the good news of the kingdom.... they are out of season for this message.
The apostles never preached the good news of the kingdom.... they preached the ministry of reconciliation. JW's do not preach this. If we preach another gospel that the apostles didn't preach, we are cursed according to scripture. (Gal. 1: 8-9)
