Hello friend greetings to you, hope you are doing well and good there.

You have said that heaven exists since God created the world. So is the Hell too. Ofcourse if we don't repent for our miss deeds, we will go to Hell. Heaven is for good people and Hell is for bad. The phenomena of Karma do exist in life. It's a famous saying, What you do, so shall you reap.

I wish you very best of luck in this contest.
