The idea that the FDS has to be a "class", not one person. How about each individual Christian being a faithful slave that gets "rewarded" with a promotion(over domestics) for being faithful and discreet? Who says every parable has a prophetic meaning?
If the 144,000 is a literal number, and the 24 elders are the 144,000, which is literal? Why can't they both be figuative?
and the list goes on.........
