In his memoir, Everything Sad Is Untrue, Daniel Nayeri tells the gripping story of his mother’s conversion from a devout Muslim background to a saving faith in Jesus Christ. She gave up wealth and social status, eventually being forced to flee from Iran under a death threat. But she was willing to pay the price. Nayeri writes about one example of her costly faith:

One time she hung a little cross necklace from the rearview mirror of her car, which was probably a reckless thing to do. ... My mom was like that. One day after work, she went to her car, and there was a note stuck to the windshield. It said, “Madame Doctor, if we see this cross again, we will kill you.”

To my dad, [who is not a Christian], this is the kind of story that proves his point. That my mom was picking a fight. That she could’ve lived quietly and saved everyone the heartaches that would come. If she had kept her head down. If she stopped telling people. If she pretended just a few holidays a year, that nothing had changed. She could still have everything.

My mom took the cross down that day. Then she got a cross so big it blocked half the windshield, and she put it up. Why would anybody live with their head down? Besides, the only way to stop believing something is to deny it yourself. To hide it. To act as if it hasn’t changed your life.

Another way to say it is that everybody is dying and going to die of something. And if you’re not spending your life on the stuff you believe, then what are you even doing? What is the point of the whole thing? It’s a tough question, because most people haven’t picked anything worthwhile.
