If God were wasteful, God would not be God.
If by “want” you mean “need” or, worse still, “lack,” I can’t agree with that. Also, the word “agenda” has too many negative connotations. Apart from this, however, I think most of us would agree the reason G-d gives every person a mind, intellect, and free will is to show His love for us by not creating us as automatons. Further, by means of free will we come to know and love G-d at a much higher level than if we were compelled to love and worship Him. We are created in G-d’s image, with the power of reason and emotions. But we are not miniature gods. Instead, we are limited by human reason and human emotions. There is also in Judaism a belief that G-d created the universe partially incomplete, and it is our job to complete it by means of transmitting our love and charity to other beings, human and otherwise, and using our reason, imagination, and creativity for the care and enrichment of others.
Even the dogs eat the scraps that fall from the rich man’s table or so the Gospel says.
And you know this why?
