Timothy Dalrymple's recent Philosophical Fragments post is loaded with not only fragments but lots of philosophical holes. "Mistaking God's Will for Our Own" has numerous problems in its logic. He fails at establishing a basic premise to start with. How can any human or group of humans even come close to determining what God's will is? He himself notes that we are imperfect while God is perfect but fails to take that notion to the next logical step. We can't know "God's will." In practice God's will has to be our will. It can never be anything more than our own biases and interpretations that creates this "will." So form start to finish God's will is our will. If that is a mistake then it is an innate mistake that cannot be otherwise.
This, of course, only matters if you fail to see the huge assumption underlying the whole argument: God exists. No one has yet provided any proof that God actually exists. Basically God is a human fabrication and therefore leads to the same conclusion anyway. God's will is our will. Religious people can dress it up in any number of arguments they want but the result is the same. Theists choose to believe in God just like they choose the type of God they prefer and the "religious experience" they want. God and religion are a convenient set of ideas that can be used to reinforce and justify what individuals and groups want to be true whether they are or not.
