Why Is God Good?
If God is powerless over His goodness, then He does not possess all power.
Therefore, God could be without His goodness. He having all power over all things, including His goodness.
What then is to be made of the continuity of His goodness? If it is in fact the case that His goodness is not necessary.
Whatever it is, it is not goodness. For, as just stated, His goodness is not necessary.
If it is not goodness, then only one remains. It is God.
God is the difference. Between goodness being. And goodness being not.
If that helps the matter any.
