Because there is a law such as gravity, the Universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the Universe exists, why we exist. . . . It is not necessary to invoke God to light the blue touch paper and set the Universe going.
Hawking is right: the god he describes does not exist. The true God did not simply set the cosmos in motion. He does not merely inhabit the gaps in our explanatory theories. Rather he upholds his creation, including the laws of physics, at every conceivable moment. Without his doing so, it would cease immediately to exist. A god who is subsequent to the law of gravity is definitely not the God of Abraham, Isaac and Jacob who became incarnate in Jesus Christ. Thank God there is no such god as Hawking conceives of him.
