From the back of the car: “Mommy, what’s God?”

I told him that “God” is a word we use to describe all the good things in the world, and that since no one completely understands exactly what God is, people have different ideas about it and sometimes disagree. Also, that although you can’t see God, sometimes you can feel it inside yourself. Which is an oversimplification, naturally, but he is only 4 after all.
