In Proverbs we read, "Train up a child in the way he should go and when he is old he will not depart from it." We infer that this is a guarantee: if we do the right things as parents, our children will necessarily turn out right. Two problems with this: First, our experience. We train our children in the right way - but they DO depart from it. Second, we look at God. In Isa. 1:2-3 God, the perfect Father, laments how his children have gone astray. Taking this verse as wisdom literature helps us. We get clear guidance from Deut. 6:4ff.
