Large Catechism: Long Life (LC I 134-149)

"Where do so many rogues come from that must daily be hanged, beheaded, and broken upon the wheel? Don’t they come from disobedience to parents, because they will not submit to discipline in kindness? By God’s punishment, they cause us to behold their misfortune and grief. For it seldom happens that such perverse people die a natural or timely death.

But the godly and obedient have this blessing: they live long in pleasant quietness and see their children’s children (as said above) to the third and fourth generation" (137).
