Well we can wallow in cynicism and blame.
Or we can be constructive and remind people, now that mortal man has disappointed them, of where hope always was found. It’s not like asking Santa Claus for a puppy though. It requires a heart and soul investment in the Lord of Hosts.
And we can recognize that we made a mistake. Which is step one in never repeating it. It seems many just want to pretend their mistakes don’t have consequences.
People who forget their history are doomed to repeat it. People who intentionally ignore it will suffer the same.
