Why is heaven worth the effort required to reach it?
EDIT: I'm asking this in good faith. I am a (admittedly very bad) Catholic and I'd prefer to live as a good Catholic, but I find it very difficult. I'm clearly being downvoted because nobody believes that I have good intentions so I guess I need to clarify that. Downvoting stops people from seeing my post and I want to have a good faith discussion with people which I can't do if people aren't charitable and assume that I'm dishonest.
Getting to heaven requires so much effort and it involves so much suffering that I don't even know if it is worth it. I think primarily because it is a matter of faith; if heaven exists, there is no way to prove it. There is also no way to comprehend what it is like without experiencing it firsthand. The things that I can experience in this life aren't a matter of faith and they don't have to be proven, because I can know them through experiencing them. I don't have to have faith that the stove exists, that it is hot, and that touching it will burn me. I can prove that it objectively does exist, that it is hot and that heat burns my flesh which causes me to experience pain. I don't have to exercise faith to prove that pain exists, because I can directly encounter it.
How should I believe that heaven is worth its price in suffering if I can know the self-evident reality of suffering but not of heaven? I can experience and know what this life is like but I can't experience and know what comes after. I know what I can do to give myself relief from suffering in this life but I supposedly get punished with more suffering in hell for doing that. Why would I be punished for not doing what I don't know?
