Fair enough. People are not interested. Aside from the fact this makes it even more pointless, what is the logical conclusion about the fate of those who do not listen? If they are all to be destroyed then God's justice is called into question. If they stand a very good chance of getting through thanks to Jehovah's compassion then what's the point of preaching?
If you want to bring up the story of Noah as an example then all that shows is that God was happy to drown innocents. I recall the Bible Story Book picture of the mother with a babe in arms for example. All that means is all but a handful of the worlds population will survive, the vast majority never even reached with a meaningful message let alone able to make an informed choice.
ITKH - where do you really stand on this?
