A couple weeks ago I gave a presentation on the existence of God. The following Monday I was asking some follow up questions at Bible Study.
Here was one of them:
"OK, so let's suppose this God you've described does exist. How do you know the Christian revelation is the valid one? Especially when there are other people like Jews, Muslims, and Zoroastrians who say its their religion?"The kids who've gone off to college will tell you this is the most common question they get asked. And yet, the response I got that evening from the high schoolers... was mostly silence.
They're not ready for college.
