This is about the parable of the person who built his house on sand and another who built his house on rock. Floods came and the house built on sand was washed away and the house built on rock was not.
In this telling the house built on sand represents magical thinking and the house built on rock represents reason and science.
The question is which to attach to. So, what are the odds?
It would be scary if the odds were 50/50. Some religious folks say “I’m either right or wrong, so the odds are at least 50% you are going to hell if you don’t convert.”
Are we naive when we believe any religious claims which include stories of magical acts or places? How does one choose between the thousands of magical religions with each one claiming to have the only true path into God’s favor?
As children we usually think to ourselves at one time or another “That (a miracle in sacred scriptures) doesn’t seem possible but all these adults think all of this is real, and they are right about everything else, so they are probably right about this too, plus who wants to take the chance of being tortured forever and ever, so we go “all in” because we want to be safe and secure forever and ever.
