Oh - later we read of them responding positively when He returns. But in this first encounter, the extent of His power is a frightening thing. It's no small matter. The power and authority of Jesus. With all spheres of the Cosmos Jesus works from His position of power.
Obedience is demanded.
There is no option. But with humanity it is different. With humanity Jesus has chosen to work from a position of authority . He calls for our submission. He invites our obedient response.
