Sin leaks, and creeps, and repeats. The multi-generational narrative form of the Old Testament doesn't hide this from us, in fact, it paints it vividly in painful details of children living with the consequences of their parent's sins and, all too often, allowing those sins to form patterns that they live out themselves.
“We are ghosts or we are ancestors in our children’s lives. We either lay our mistakes and our burdens upon them, and we haunt them as ghosts. Or, we assist them in laying those old burdens down, and we free them from the chains of our own flawed behavior, and as ancestors, we walk alongside of them, assisting them to find their own way, and some sense of transcendence.”
