It is through meditating on the Word and the enlightenment of the Holy Spirit that Christ in His fullness is known.
The piece of armour known as the “sword of the Spirit” is the only piece of armour that has the ability to cut, wound, and hurt our enemy, the devil. It’s not the Bible lying on your coffee table that makes the enemy flee, but it is the Word of God hidden in your heart, activated by the power of the Holy Spirit, and spoken in an appropriate situation.
It’s similar to what is spoken when Jesus said in John 6:63, that “…….The words that I speak to you are spirit, and they are life.” The Word by itself doesn’t make us free. It is the Word we know and speak that will deliver us (John 8:32). That is, ‘know’ after many hours of honest, trusting conversations with God (heart of meditation upon the Word), and ‘speak’ out in full confidence that God is going to fulfill His Word.
Why is the Word so effective? It’s because it is the WORD of God. It has authority and power. God’s Word supersedes all authority on earth. It supersedes even Satan.
It is the Holy Spirit that wields this Word (Sword, Eph. 6:17) as it is spoken in faith. Speaking God’s Word in faith brings the Holy Spirit into action. In Luke 4, we see Jesus using the Word to defeat Satan. No matter what the temptation was the answer was the same, “It is written.” Likewise, the Christian soldier must have God’s Word hidden in his / her heart (Psalm 119:11) so that the Holy Spirit may bring it into action at the appropriate time to accomplish a complete and total victory. It’s yours!
