For Israel is a young lad, therefore I love him (Hosea 11:1).
Historically, the Jewish nation is one of the oldest in existence. In terms of behavior and reactions, it is the youngest.
One prominent difference between children and the elderly is that children heal much more rapidly. Children are resilient. When they fall, their bones do not break as easily, and therefore they are quickly back in action. An elderly person who falls is likely to sustain a severe fracture and may remain disabled for a long period of time.
No nation has experienced the traumas that have repeatedly befallen the Jewish nation. Expelled from its homeland and subjected to inquisitions, pogroms, holocausts, and hostility everywhere, the Jewish nation reacts with the resilience of a child. Its bones bend rather than break. Injuries heal quickly, and while still smarting from its wounds, it rises and is back into action.
We individuals should learn from the nation to never grow old in this sense. No one's life is free of distressful experiences and trauma. At any age, we can retain the vigor and resilience of youth and go on with the business of creativity and constructive living.
