I liked Jeremy’s comment about how Christians don’t believe in miracles these days:
When it comes down to it Christians don’t really believe in miracles anyway.
When they hear of a person claiming “God told me to kill my children” they instinctively know that person is crazy. We all do. [It] doesn’t matter what God told Abraham —when it happens in the real world Christians respond like anyone else. If I claimed to have literally moved a mountain with my faith no Christian would believe me.
Christians go to a doctor when they’re sick. They may pray as well, but they’ll definitely go to a doctor, and they’ll look at you like you’re crazy if you don’t.
Christians will wear seat belts and follow safety instructions and buy insurance and save for retirement just like anyone else. They may claim that they believe God heals and God protects and God provides, but it doesn’t tend to turn into action.
In my experience, that’s true. When it comes to the real world, Christians act just like atheists. The ones that don’t act like atheists end up in jail (for child abuse by withholding medical treatment, for instance) or a mental institution (for listening to the “voice of God” in their head).
