Do you believe in Heaven?
Yes. But I respect those that don't believe on it so, hopefully they'll also respect my belief on it.
Do you expect to go to Heaven, when finished here on Earth?
Yes, I'm expecting to be in there and it's not just when you pass away here on Earth you'll get there surely. This is where the belief of each religion comes and I don't wanna expound on it because it's gonna be a long debate. So, I'm all good if someone believes in heaven or not but not with long arguments.
Optionally, please feel free to discuss why you believe and what you think it will be like, i.e. Will your favorite pets and friends be there and easy to find?
It's paradise, where you don't have to be problematic about daily living and there's no more sickness in there. As for the pets, I don't think that we'll see them there because from what I know, they've got no soul. And with our friends, possible.
How will you find them, will we have "Apps" for that?

We'll just gonna know that soon.
