Even if the scripture meant what the organization says it does, the doctrine is not applied accordingly.
I always appreciated this comparison -
Light getting brighter (what it means)
I see an object. It looks like a car. It's a 4-door sedan. It's a blue 4-door sedan. It's a blue Toyota sedan.
Light getting brighter (as it really happens with the WBTS)
Jesus said drive a car. Jesus said drive a 4-door sedan. Jesus said drive a Cadillac. A Cadillac is a showy display of one's means, so drive a Ford Focus. Jesus walked everywhere he went, so don't drive - walk!
