Faith is believing stuff without any real evidence.
My mum is obsessed with Jesus. She's a monster due to her schizophrenia and has no clue about it. They think my dad and I wanna kill her and are "the evil ones" and she is 100% SURE that JESUS is witnessing all this and will save her sooner or later while we'll burn in hell.
After my failed attempt last year, she told me that if I started praying everyday, Jesus might allow me to go to heaven with her.
It's really sad but she really believes this and if you tell her things like, "Hey, did you know that you wouldn't be a catholic if you had been born in the Middle East but a Muslim?" she just ignores you and says Jesus is her only saviours and only real thing.
I'm really sorry for her but I think the best to do with these kind of people is ignoring them.
It doesn't matter what they think is gonna happen to us after our death, we just can't change their mind.
I'm still in this world only because of my dad. Religion has nothing to do with it. I just don't wanna destroy his life because he might really have a heart-attack or stroke once he finds out I'm dead.
