“If you believe a truck is coming toward you, you will
jump out of the way. That is belief in the reality of the truck.
If you tell people you fear the truck but do nothing to get
out of the way, that is not belief in the truck. Likewise, it is
not belief to say God exists and then continue sinning and
hoarding your wealth while innocent people die of starvation.
When belief does not control your most important
decisions, it is not belief in the underlying reality, it is belief
in the usefulness of believing.”
“Are you saying God doesn’t exist?” I asked, trying to
get to the point.
“I’m saying that people claim to believe in God, but most
don’t literally believe. They only act as though they believe
because there are earthly benefits in doing so. They create a
delusion for themselves because it makes them happy.”
“So you think only the atheists believe their own
belief?” I asked.
“No. Atheists also prefer delusions,” he said.
“So according to you, no one believes anything that
they say they believe.”
