Passover - Progress to Redemption

This Shabbat we begin the second book of the Torah in which we read about the enslavement in Egypt and the subsequent redemption process. On Passover we drink 4 cups of wine to symbolize the four steps of redemption mentioned here. I will take you out, I will save you, I will take you culturally out of Egypt, and I will redeem you. Some even say there’s a 5th cup – and I will bring you to the land of Israel.  

The question is asked why 4 cups of wine to represent the four steps of redemption? Why not four matzos or four pieces of meat?  Rabbi Naftali Tzvi Yehudah Berlin explains that this was a process the Jews had to go through in order not just to be taken out of Egypt but to actually change from being slaves to becoming to Jewish people.  

Wine is like that. It is a progression. We drink one cup and we feel it a little bit, we drink the 2nd cup and we feel it more and more. it builds on itself and takes us from one place to another if done correctly. 
The point is an important one – that change and redemption does not happen in the blink of an eye, it happens rather through a process. Human beings don’t change easily but they can change. Each of us is more flexible than we realize, though often we are afraid of change.  

And so part of the message of these parshiot and the redemption from Egypt is that God is there with us to help us and that there is a process to undergo. Positive change doesn’t just happen overnight. So too with our own spiritual lives. we have to engage in the process, we have to cry out to God to begin the process, but then God will help us. What process can we begin this Shabbat to help us to progress toward becoming more morally and spiritually developed human beings and Jews?
