It is his duty to ensure the destruction of a irreconcilable corrupt race, his own people, or to send hem forward with his Word backing them as being worthy to go ahead.

Yes he can control the weather.
The amount of solar radiation even.
Even which volcanoes erupt or not.
And earthquakes as well.
But his true power really exists in the power of his Word.
Which all things unseen obey his orders.
It is an elected responsibility, because he was chosen as the One to save us all.
By all rights granted, this is his Planet, and his Ark, and we are all on it.
