We are told over and over that our prayers work. Yet we often find it difficult to ask. One of the reasons is that we may not feel worthy. After all, what right do I have to ask HASHEM to change things? Can I say that I have done my part so well, that I can ask HASHEM to intercede on my behalf?
Through the well-known episode of Rochel begging HASHEM to bring back the Jewish People from exile, we are brought to understand the power of prayer, and one of the systems that is most effective to get our prayers answered.
