These very sobering words are often invoked at moments of great personal distress to express our faith and trust in the Divine wisdom and justice.
People who have suffered deep personal losses, such as destruction of their home by fire or the premature death of a loved one, or who have observed the widespread suffering caused by a typhoon or an earthquake, may be shaken in their relationship with God. How could a loving, caring God mete out such enormous suffering?
It is futile to search for logical explanations, and even if there were any, they would accomplish little in relieving the suffering of the victims. This is the time when the true nature of faith emerges, a faith that is beyond logic, that is not subject to understanding.
The kaddish recited by mourners makes no reference to any memorial concept or prayer for the departed. The words of kaddish, "May the name of the Almighty be exalted and sanctified," are simply a statement of reaffirmation, that in spite of the severe distress one has experienced, one does not deny the sovereignty and absolute justice of God.
Our language may be too poor in words and our thoughts lacking in concepts that can provide comfort when severe distress occurs, but the Jew accepts Divine justice even in the face of enormous pain.
