Their excitment of being able to have authority
over devils gave Jesus joy. He commended
them and showed them that Satan has been
defeated. "I beheld Satan as ightning fall from
heaven."
Jesus assured them
that they had complete
dominion over Satan;
that they didn't need
to fear him, but that
they could tread on all
serpents and scorpions.
It is interesting to know that these words were
spoken to the Seventy rather than the Twelve,
because it shows that all believers have power
over Satan if they will take and use that authority.
