The Word of God is the Holy Spirit’s sword (Ep 6:17) … so God’s sword is also ours, our primary weapon in spiritual warfare. Without it we’re no threat to the enemy, more a target than a soldier. (2Ti 2:3)
And this weapon, the Word of God, is alive … powerful! (He 4:12) To be effective it must be an extension of our hearts and minds, interconnected with us (De 6:6-9) … it’s Christ Himself in us (Jn 1:14); both spirit and life. (Jn 6:63)
So how do we wield this supernatural sword? Get it into the Spirit’s hands, interconnect with it?
Christ’s example when Satan attacked Him was to quote the Word, saying repeatedly, “It is written.” (Mt 4:4, 6, 7) By hiding God’s Word in our heart we arm the Spirit for war, equipping Him to defend, protect, feed (De 8:3) and heal us, cleansing us of our lies and strongholds. (Ep 5:26) It’s hard to wield this particular sword unless we can quote it, but merely memorizing scripture won’t do; we must be constantly meditating on it (Ps 1:2), saturating ourselves with God in His written Word. (Jos 1:8)
