The phrase “resist the devil” is found in James 4:7 where the apostle James exhorts believers to resist the devil in order to cause him to flee or “run away” from us. To resist means to withstand, strive against, or oppose in some manner. Resistance can be a defensive maneuver on our part, such as resisting or withstanding the temptation to sin. Or it can be an action we take to use the only offensive weapon in the full armor of God (Ephesians 6:13-18), the sword of the Spirit which is the Word of God. Using the Scriptures to expose Satan’s lies and temptations is the most effective way to strive against and defeat them.
