Colossians 2:15:

And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.

Notes on Colossians 2:15:

“It” here is the cross.  Jesus triumphed over the devil and all his principalities and powers on the cross, not in hell.  (This matter is part of a long discussion elsewhere.)

Jesus Christ defeated the devil for you.  The devil and his subordinates have been stripped of their power.  (The word spoiled actually does mean stripped!)  That means that the devil does not have any power over you other than the power that you give him.  He does not have authority, but you do.  The devil’s ploy is to get you to use your own authority against yourself by speaking the wrong things out of your mouth.  The devil can't make you do that, but if he can trick you into doing it, you will end up ruining your own life with your mouth.

There is no reason to fear Satan.  He has no authority over you.  You are seated with Christ in heavenly places far above him.  He cannot defeat you unless you allow him to.  His only real weapon is deception.  He can’t win unless he can trick you into believing, speaking and doing the wrong things.
