During my days as a teacher—in my little corner of the world, inside the four walls of my classroom, my students were good kids. They liked Jesus. They went to church and participated in youth group. They loved and respected their parents. And let’s be honest. They, of course, loved their Bible classes with me. I have no doubt—even today—that most of that is true. But what I neglected to realize was eventually they would have to leave the comfort of their homes, classrooms, and neighborhoods.
