I was rather surprised to read what Professor Bart D. Ehrman had to say in a recent article What Jesus Really Said About Heaven and Hell.[i] published by TIME on its website.
He states that there are over 2 billion Christians in the world, the vast majority of whom believe in Heaven and Hell and goes on to say that, ‘the vast majority of these people naturally assume this is what Jesus himself taught. But that is not true. Neither Jesus (as), nor the Hebrew Bible he interpreted, endorsed the view that departed souls go to paradise or everlasting pain.’
