You are so tunnel-visioned, you can't see past your own bias and grandiose ego.
What do you know about disease and human suffering and the afterlife? You've obviously rejected God already - therefore, rejected any of the truths behind all of these things. Your mind and heart are already sealed. You and I are on completely different planes of understanding as a result- and it's as if we are back to back looking at two different worlds and trying to argue about it.
Who do you think you are that you can decide what our Creator and Sustainer does, does not do, gives riches to, gives famine, gives disease to ..... ??
He can give any of that stuff to whoever He pleases. And your opinion on the matter means NOTHING.
That is why I am not atheist, but a Believer.
