It’s ironic that Knoch believed God was unimaginably powerful, yet would be unable to carry out His plans unless everything was determined beforehand in advance; as if God couldn’t cope with contingencies.
Human architects/builders carry out their plans and bring them to conclusion. They do this even in the face of unexpected difficulties. Can God do any less? Of course a tornado or earthquake can come along and disrupt a human architect’s plans. Fortunately for the human race, God can handle tornadoes and earthquakes.
