How does Reformed Theology consider passages that may imply that God is the "subject of sufferings"?

In _A Dissertation Concerning the End for which God Created the World_, John Edwards makes the following statement, >Because it is evident, by both Scripture and reason, that God is infinitely, eternally, unchangeably, and independently glorious and happy: that he cannot be profited by, or receive anything from, the creature; or be the subject of any sufferings, or diminution of his glory and felicity, from any other being. It is however _not_ immediately evident by either Scripture or reason to me that God is infinitely and unchangably _happy_, nor that God is not subject to _any_ sufferings. In fact, numerous passages in the scriptures describe instances in which God is _angry_ or _wrathful_ and is thus unhappy, and also instances when God is _greiving_ or _sorrowful_ and is thus subjected of suffering. For me personally, the sufferings of God, especially the contrast between those sufferings caused in him by the Acuser, Man, and those caused in him by the ministry of Jesus, is a central theme of the narrative of redemption. How are passages that contain these themes handled by Edwards and other Reformed teachers that follow him, in the context of his statement here?
