Children are a lot more likely to get the message if you transmit it in the classroom of everyday life-sitting at home, driving somewhere, at bedtime, at breakfast, at dinner. Spiritual reality is best communicated in real situations, not in formal presentations. There are a lot of things a parent can delegate-cleaning the house, mowing the lawn, washing the car. We can delegate the teaching of algebra or soccer or piano. But the Creator makes it very clear that parents cannot delegate to others the spiritual equipping of their kids.
Home is reality, and spiritual reality is what they are starved for.
A church or clergyman or book can show them the facts, but parents are divinely positioned to show them the reality. Many of the most personal spiritual realities are communicated when life provides teachable moments. He learned the real-life lesson that day that harbored anger is not worth it. Parents with their spiritual radar on look for these natural opportunities to make faith come alive in everyday situations. Something dirty they heard at school becomes a moment to teach the beauty of what is pure.
