One of the most important principles of spiritual warfare is that you must use your authority against the enemy. Jesus said, “I give unto you power [power is the Greek word exousia, which means ‘authority’] to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you” (Luke 10:19, KJV, emphasis added). Now some people say you can’t be hurt by the enemy because Jesus says, “I give you power.” But that’s only if you use the authority.
Just because you have been given authority doesn’t mean you’ve used it. If you don’t exercise your authority, you cannot claim the second part of that verse that says “nothing shall by any means hurt you.” We must exercise our authority, and some of the ways we do that are through prayer, through binding and loosing, and through commands and decrees that we release through our words. So it’s important to exercise your authority over the enemy on a consistent basis.
You need to bind and rebuke in the name of Jesus any demon that will try to block your path or your way. Psalm 91:13 says, “You shall tread upon the lion and adder; the young lion and the serpent you shall trample underfoot.” The enemy is under your feet. That represents total authority and victory. Make this your confession, and go forth in victory and in the power of God.
