The God of peace will soon crush Satan under your feet.
The grace of our Lord Jesus be with you.
(Romans 16:20)

Satan cannot have power over us unless we give it to him.  None the less, he's smart, crafty, and clever.  Fortunately for us, God is more powerful than 10,000 Satan's and will eventually destroy him.  Even though we know Satan's fate, we must keep our guard up at all times and not let Satan take advantage of us during weak moments.  Be strong and aware of his games and temptations.
