Being unique means being different. The Jewish people are certainly unique and Va-ayra teaches more uniqueness. Moses, selected by G-d, is told that he will lead the Israelites out of the land of Egypt with the assistance of Aaron. Moses becomes a unique leader.
The story which follows is the most unique escape from any slavery ever. G-d brings the ten plagues against the Egyptians. Those who choose to explain these events by natural mean - earthquakes, lava flows from volcanos - are free to do so, but such misery inflicted on the Egyptian people is unique.
But what does it teach us? Does it teach that whenever the Jewish people are in trouble they can look to heaven and ask for the ten plagues? No, it certainly does not...the ten plagues were unique and will not occur again. Does it teach us that we have to find a Moses in our midst whenever we're in trouble? In a way.
What the story teaches us is that each of us can be leaders. Not necessarily leading our people from darkness to light - such leaders are very rare, and thankfully so are the circumstances through which we may need such a leader. It teaches us that there are always paths through which we can guide others....that as Jews we should guide others as best we can. We were reduced to crawling as slaves in the mud, yet we still survived. We must not reduce others to such shame and we should guide everyone out of their Egypt, whether it be a social problem, a mental one or perhaps even a physical one.
In this world we too often sit back and wait for others to show us forward. It is the Jewish people's task to take the first step towards the improvement of our world. Thus, after reading this, take a path. Choose a way of life, choose a part of the way. Action is greater than thought. Then, when you start to lead towards the greater good, you also reaffirm your belief in the covenant which was reminded to Moses at the start of the Sedra, by stepping in the path of G-d.
