The answer differs depending on which religion/sect/philosophy you adhere to, but God is usually attributed some sort of emotion, or at least a will, because without it the belief in God can’t serve a societal use.

Say you assume a God without emotions. From this it results that nothing we may do or fail to do would impact them, so there are no sins, no divine laws, prayers and rites are useless… So your belief can’t be a religion; nor can it be used to control people. There’s no physical use to preaching belief in God, and not much of a metaphysical need either since God doesn’t care whether you believe in them. “God” becomes a concept like the laws of physics, there’s not even much meaning in considering it as a being. There’s little difference between an emotionless God and no God at all. So all religions will personify God to some extent.
