The small Oingo Boingo tribe have occupied the same hidden valley of Papua New Guinea for millennia.
The jungle-tribe remains oblivious to the outside world, just as the outside world remains unaware of their existence.
Given this scenario how does God communicate with the tribe?
Not even the most fervent and adventurous proselytising missionary has come across their village and the tribe are perfectly happy & comfortable with their existence and feel no need to seek out other human contact.
Why is God happy for generation after generation of the Oingo Boingo tribe to burn in hell?
