Generational restoration

The very last word of the Christian Old Testament and the Jewish Prophetic opus is a call for reconciliation between fathers and sons, and by implication; mothers and daughters, sons and mothers and daughters and fathers. It's a call to generational reconciliation and not just within individual families, but within the whole covenant community.

This is how is reads in The Message:

He will convince parents to look after their children and children to look up to their parents. If they refuse, I'll come and put the land under a curse.

The curse issue seems pretty harsh, so it must mean that this is really important to God.
