The entire chapter of Deuteronomy 11 is worth concentration for an extended period but pertinent to the title is this section which reveals that God is indeed the God of practicality and reality. How is it we are to transfer to our children the seriousness of God and His Word? Of all the ways many Christians attempt to influence their children within the church, here is a prescription from God which challenges all of our ecclesiastical youth oriented dog and pony shows:
19 Teach them to your children, talking about them when you sit at home and when you walk along the road, when you lie down and when you get up... 21 so that your days and the days of your children may be many in the land the Lord swore to give your ancestors, as many as the days that the heavens are above the earth.God is not prescribing magic, cleverness or zippity-zappity soul patch bohemian Jesus coolness, God is prescribing a way of life. Maybe in all your business to get your children into the hands of other people to convince them God is true, you have failed to do the very thing you should be doing most. But maybe that is because you really aren't all that interested in talking about God all the time because you don't have him on your mind enough to talk about God's Word or God Himself when you sit at home or when you walk along the road (or drive your car) because you are always preoccupied with other things.
You want to teach your children about God and His Word? Do this, first and foremost because if you are not doing this then all the effort of people, other than you-the parent-, is undone by your apathy and fortuitous example.
