That’s right! If you want the sword to be in your mouth, you’ve got to be a "sword-swallower." No Sword In, no sword out! If you want the Word to come out when you’re attacked by Satan, the Word has got to be Locked and Loaded IN your Spirit.
Now when you and I - as followers of Christ - are sensitive to the Holy Spirit in our lives, the Scriptures that we have hidden in our heart will become a Sword in Our Mouth against the devil and his forces!
Rom:8:26: Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
In fact, I believe that a child of the King Of Kings should expect the Holy Spirit to help by bringing to our remembrance the scriptures to fight off Satan when we are tempted and in battle. 1Cor:15:57: But thanks be to God, which giveth us the victory through our Lord Jesus Christ. "OVER ALL THE TEMPTATIONS OF THE ENEMY."
