Rabbi, I have two questions for you:
1) Do you make up these questions or do you receive them from real people?
2) If G‑d is perfect, why did He create us? A perfect being isn't missing anything, so why would He need us? And if He doesn't need us, is our life meaningless? Are we just some divine experiment?
Answer:
Some questions are too esoteric to answer. It is beyond our limited understanding to reach a solution to all the mysteries of the universe, and these may always remain mysteries. So I will have to skip your first question and only deal with the second.
You are absolutely correct: G‑d, being perfect, was missing nothing before creation. There is no possible need that this world can fulfill for Him. He doesn't need anything.
So creating us could not have been in order to fulfill a need. It was something G‑d chose to do. He doesn't need us, He wants us.
What does G‑d want from us? The one thing He didn't have before creation was a relationship. He was alone. What He wanted from this world was a relationship with free beings. So He created us and gave us ways of connecting to Him — the mitzvot.
But we can't say that He needed this relationship with us. He may have been alone before creation, but he was still G‑d — perfect and missing nothing. He didn't need a relationship — He wanted it.
Does this make our life unnecessary? Does the fact that G‑d doesn't "need" us make us less significant?
No, on the contrary. When we have a relationship with someone just because we need them (such as a cleaning lady, or a family doctor) then when that need has been fulfilled the relationship ends. Your connection is dependant on them providing a service, and will only last as long as that service is needed.
But when we have a relationship with someone simply because we want to, because we have chosen to connect to them, then that bond is intrinsic. We don't love them because of what they do for us, we love them for who they are — and that is forever.
G‑d doesn't need us; He wants us. He didn't give us commandments because He needs them to be fulfilled, but because He wants us to relate to Him. If we were created because G‑d needed us to do something, then we would be secondary to that mission — once the mission was fulfilled we could be disposed of. But G‑d needs nothing. He chose to bring us into being as a pure act of love.
That is the test of true love: if my beloved could no longer provide me with my needs, would I still love him or her just for being my beloved?
By creating us, G‑d answered yes.
This is wrong. The rhetoric that God created us but doesn't actually need us is dangerous. If God doesn't need us, then humanity in general isn't needed, thus, completely worthless!
God is the only one who has actual needs. To argue that human beings have needs is silly, as no human has asked to be born to begin with and doesn't even need to be here on this Earth. God needs you! You are needed! Don't let anyone tell you otherwise!
G-d WANTS us
Elan, a question. Why do you think our Creator has needs? Could it be that he needs to pay bills or buy groceries?
From our human perspective, some scientists perform tests to have positive outcomes from test subjects. Our Creator is not like human beings but uses our created minds consciousness to choose our paths for good or evil during our short life spans. Is His test succeeding now that the nations attack Israel and the Jewish people, and antisemtism reigns?
G-d doesn't need us anymore that we need to have cancer. Don't let anyone tell you otherwise.
The rabbi is correct. A perfect being needs nothing but desires companionship in the form of Torah observance from His Creation. Just as human beings desire companionship whether by friendship or family or marriage or Torah observance. Since we are created in His image albeit with moral frailty we can also understand a few things about who He is and His Nature.
