If God existed and heaven was real, it wouldn't make any sense. You are supposed to go to heaven if you accept jesus christ and the teachings of the bible. However once you get to heaven, how are you ever going to be happy? Knowing billions are in hell getting tortured forever, not to mention that your relatives, father, mother or child could be there too, how can someone ever enjoy heaven knowing his/her son is in hell being tortured forever? How is God going to make sure that there is no crime in Heaven or that everyone is going to be happy? Is he going to transform us into robots?
Another paradox of heaven:
I'm walking with my girlfriend and a robber tries to rob us and shoots her. I was a believer but she wasn't.
50 years later, the robber and I both die, the robber a few years before dying accepts jesus christ and repents his sins.
We are now both in heaven and I'm supposed to be happy knowing that not only my girlfriend is going to be eternally tortured but also that I'm going to spend all eternity living with the man who actually killed her.
Furthermore if she lived maybe she would have accepted jesus christ just like the robber did yet she didn't have the chance to do so.
What about all the kids that die prematurely or aren't even born, do they go to heaven? It's unfair that they would go to heaven instantly yet we have to pass the test.
Im a believer , and i think If you do not want to see your mother , father , siblings (family) torture in hell forever while you are in peaceful life in heaven. You must invite them to accept Jesus Christ as their Lord God and Savior.
Just try to convince them , Bible says in verse John 4:16 Jesus saith unto him, I am the way the truth And the life no man cometh unto the Father but by me,
