"...A God who is but a reflection of human frailty"

An interesting quote I came across, attributed to Albert Einstein, in a column for the New York Times Nov 9, 1930:: “I cannot imagine a God who rewards and punishes the objects of his creation, whose purposes are modeled after our own—a God, in short, who is but a reflection of human frailty.”

I've always found the worship of God a strange thing to do.  I did not choose to be created, and I have only very limited control over my destiny.  Why would God expect my praise for His creation? Why would he want it?
