“Whoever saves a life is credited as if they had saved an entire universe.”

Not all of our decisions are as momentous as God’s original, first decision.  But in the shiur to Chapter 2, I use this mishnah to argue that at least some of our decisions are comparable in magnitude.  The saving of one life is credited the same as the saving of the entire universe from destruction, which is to say, saving God’s entire creative plan.  That suggests that we humans are capable of making at least some decisions at a comparable level of importance even to the original Creation.
