Parshas Bo

The mitzvah of pidyon haben the Torah tells us to consecrate our firstborn sons to Hashem’s service, for Hashem killed all of the Egyptian bechorim and the jewish ones were saved.
What is the reasoning behind this - because Hashem punished the Egyptians through their firstborns all the future firstborns born into Klal Yisroel become holy? Why is there a need for a tradeoff?
Let us try to understand why was it that the firstborns were the ones who were punished.
One of the basic concepts in yehadus is that Hashem is the beginning of everything. It is He who created and preceded the world and before that there was nothing but He. Paroh and the Egyptians didn’t want to accept that as the truth. Thus they worshiped sheep which is the first of the horoscopes to show that the beginning and everything that comes after that is contributed to the stars and mazalim. As Hashem created his nation and thus made his name known to the world He wanted to show and prove that it is He who was first. The way to do this was by wiping out anything that was viewed as a ‘competition’ to his oneness. That is why Klal Yisroel slaughtered the sheep for their korban Peasach and that is why all the firstborns- including those of the slaves had to be killed. In order for the bechorim of Klal Yisroel to be saved they had to purify themselves and consecrate themselves to Hashem and his oneness. Only through them being a light onto nations and showing that all beginnings channel back to Hashem could they be saved.
