At the head of this mighty mission stands the one man capable of forging the many into one - Moshe Rabbeinu. One of Moses' crucial responsibilities is toconvince the people that their future glory depends upon their channeling their individual talents into the communal good. Moshe's daunting task is made more difficult by the fact that Bnei Yisrael are entrenched in the depths of despair, enslaved in cruel bondage to a sadistic regime. They are without hope, without joy, without light. His staff turns into a snake, his hand turns leprous and then fleshy again, and he transforms water into blood.
Life can change, people can change, situations can change.
Change is the constant of our entire experience. Like the moon, which appears to fade completely, but then emerges full and shining, so we Jews are always in flux. We are always changing, always ascending, always transforming ourselves for the better. Teshuva is change. Torah inspires us to change.
