Answer: The best approach is found in the instruction given to the children of Israel by Moses more than four thousand years ago. He wrote, "Impress them on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up. Tie them as symbols on your hands and bind them on your foreheads. Write them on the doorframes of your houses and on your gates" (Deuteronomy 6:7-9).
This commandment provides the key to effective spiritual training at home. It isn't enough to pray with your children each night, although family devotions are important. We must live the principles of faith throughout the day. References to the Lord and our beliefs should permeate our conversation and our interactions with our kids.
Our love for Jesus should be understood to be the first priority in our lives. We must miss no opportunities to teach the components of our theology and the passion that is behind it. As you've said, I believe this teaching task is the most important assignment God has given to us as parents.
The reason this is such a critical responsibility is that the world will be giving your children very different messages in the days ahead. It will take them to hell if not counterbalanced by a firm spiritual foundation at home. This is one task about which we can't afford to be lackadaisical.
