The Sword of the Spirit
Ephesians 6:14-17 Stand therefore (hold your ground)
Stand therefore [hold your ground], having tightened the belt of truth around your loins and having put on the breastplate of integrity and of moral rectitude and right standing with God, and having shod your feet in preparation [to face the enemy with the firm-footed stability, the promptness, and the readiness produced by the good news] of the Gospel of peace. Lift up over all the [covering] shield of saving faith, upon which you can quench all the flaming missiles of the wicked [one]. And take the helmet of salvation and the sword of the Spirit, which is the Word of God. POWERFUL!!!!!
This passage instructs you to wear armor that serves as protection against the principalities and powers of the enemy. You have defensive armor and a powerful offensive weapon - the sword of the Spirit. A sword kept in the sheath has no value. It must be wielded – taken from the sheath and used. The Word of God is your sword. When Satan attacks your mind say, "It is written" and quote a Scripture that opposes his lie.
