Here’s a great analogy for religious differences:

Say I wanted to go to the Grand Canyon. I’d get a map that showed me how to get there from Minnesota. There might be other people going, too, from other places. Like, maybe California. When I got to the Grand Canyon, I wouldn’t sit in my car admiring my map. And I wouldn’t approach the person from California and start a fight with them because they had used the “wrong” map to get there. We’d both put our maps down and get out of our cars, since the point of the trip is to admire God’s amazing creation.
