I was lucky the priest told my parents that my brother died, was the will of God
After that they taught me that all that sort of hell crap from the Bible was not true
Never had any fear, even better, I knew it was a fantasy, not true
They did trick me a few years with Santa Claus. When finding out they lied, I was
quite angry. But then they tricked me again and said "can you play along for 2 more
years, your sisters are young, they still like it. Of course we must give you presents
like your sister, even if you don't believe. Are you oke with that? That was a smart move
Just tell the truth "Some people believe hell exist. Don't believe them. It doesn't
exist. So you can never go there". They believe their parents when young
Better tell them the truth, before you send them to a christian school.
Oh by the way, lying about Santa Claus is zero as compared to hell. In my church even
people of 80year+ still believe in hell. None of them in Santa Claus.
