The Pesach Hagadah - by Shmuel Knopfler
The Hagadah commences with shame and he ends with praise ... Why are we starting with shame? Normally a nation would pride itself with a glorious past not with disparaging remarks. We are not to remind the convert of his checkered past. The Maharal points out that in order for a person to ascertain his current position he must look into his past from where he came from. This is an integral part of Hakoras haTov, simple gratitude. A third of the Jewish people were decimated 70 years ago. Today we are resuscitated in our own land with the language of our ancestors. What a contrast to the abyss we came from. This is a clear and open miracle of HaShem. Our physical and spiritual revival manifests itself both on an individual as well as on a national level.
