If God doesn’t need us, why did He create us?

Need is not matched by tampering, but wisdom, as a wealthy doctor treats people without needing them. God is rich in the worlds, and the benefit of worship and our shortcomings in it belongs to us. It is not necessary to understand all dimensions of wisdom, it is enough to know that God is wise in his creation, just as we trust the doctor, even if we are ignorant of his decisions.
