Why is God considered all good?
I have heard God described as an omnibenevolent being most of my life. But where did this notion come from? In the bible, God is described as jealous, wrathful, angry in addition to the loving aspects. So while I definitely understand that God can be described as generally good, it does not seem to be the Core of who he is. One could just define good as whatever God does but that makes the word good meaningless.
God to me seems to be more of the ultimate authority and is beyond notions such as good and evil. Being all powerful would make dissenting opinions irrelevant as no one can hold God accountable regardless.
So when people describe God as omnibenevolent or good do they mean that literally or just that God has tendencies that way? Or something else?
