Adam is created by G-d himself and placed in the Garden of Eden, Paradise.
G-d then declared that it is not good for Adam to be alone, he must get married and so G-d created Chavah/ Eve.
What exactly was not good about Adam’s life? He lacked for nothing. There was no pollution, no elections and plenty of everything. Why does G-d say that it is not good for him to be alone?
Rashi, the classic Biblical commentator, responds strikingly by saying that it was not good for him to be alone because he may start thinking of himself as a god! In marriage your spouse reminds you that you are not G-d, hopefully kindly 🙂 One learns to consider another, to be questioned by another and to grow toward a mission and purpose bigger than oneself.
Even Paradise, and a perfect world, does not compare with being deeply challenged and transcending oneself.
