Go made man upright, but he fell in Adam and thus perished:
Ecc_7:29 Lo, this only have I found, that God hath made man upright; but they have sought out many inventions.
1Co_15:22 For as in Adam all die, even so in Christ shall all be made alive.
I get that. But I have never understood people that believe sinful people SHOULD be tortured (not just separated from God) but tortured for eternity.
Men are evil and so, in all fairness, they can't complain what God chooses to do.
Yes, that much I do agree with. It is His world and His game and He can do whatever the heck he wishes.
God created man as an imperfect sinful creature. He was the designer. One mistake and that was it? God created us so we are really His mess. I don't think we are even close to understanding any of this. :-)
