Once the Israelites understood the main thing, they could move into the teaching mode. They could "recite them to your children, and talk about them when you are at home, and when you are away, when you lie down and when you rise." Children learn by watching what the teacher/parent does; every action, intentional or not, is imitated by children and students. No teacher can teach information which is not personally understood and/or modeled. (I’ve never taught car repair and maintenance for obvious reasons!)
Now the Israelites receive more commands from God given by Moses. To insure the Israelite does not forget his/her part, he/she is to "bind them as a sign on your hand, fix them as an emblem on your forehead and write them on the doorposts of your house and on your gates." In other words, post constant reminders to yourself that you are to be very dedicated to your role as a teacher. Today we might post reminders on the refrigerator or the bathroom mirror, anywhere we look every day to be reminded of the importance of our role.
So why is this passage from Old Testament and Deuteronomy so important? Why do we need this reminder? As Christians and people of faith, we too are living a foreign land — a land of violence delivered into our homes through various forms of media, a world that has no boundaries, a fast-paced existence of constant change and continual questions. Do we need to refresh our memories as to the main point of life?
Educators know that one must have a purpose and goal for instruction. What is the main thing one wants her students to learn? As Christian educators, pastors, parents and church members we too must ask, "What is the main thing — the real focus of faith and how can we pass it to our children, our family, our friends, and others who need faith to help them through confusing and difficult times?"
