It's a frightening situation to think about the next generation growing up and not knowing anything about God. We are responsible for passing it on:
One generation commends your works to another; they tell of your mighty acts.
So what do we need to do?
Fix these words of mine in your hearts and minds; tie them as symbols on your hands and bind them on your foreheads. 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. Write them on the door-frames of your houses and on your gates, so that your days and the days of your children may be many in the land that the Lord swore to give your ancestors, as many as the days that the heavens are above the earth.
It means we need to have God's word in our hearts and minds. We are not going to pass anything on that we are not captivated by ourselves. Then we need to talk about them to the next generation - not waiting for designated times or places but as part of our everyday lives. Are you telling the next generation about God?
