IMHO, heaven is a place where we could live our lives through eternity.
I believe its a paradise consists of all of our hearts desires. A world without sickness,problems,hatred,violence,death and evil.
A place filled only with love and happiness. But who knows right? Im talking about it based on books,religious type thing belief that there is something perfect after this life and there awaits a perfect haven for all of us.
We all know that no one came back from that place and live again to tell the story. There is no evidence to support that. Having said that,
I still hope that there is a place like that after we part from this world.
I have faith and i always open the door for such possibility.
