“Take . . . the sword of the Spirit, which is the Word of God,” (Ephesians 6:17).
Why do you suppose Paul called the Word of God the “sword of the Spirit”? There’s a very good reason for that – it is the only offensive weapon in our Christian arsenal. And it is enough because Satan runs from the holy power of God’s Word. Hebrews 4:12 calls the Word of God “a double-edged sword.” Revelation 1:16 describes the God-Man, Jesus Christ: “out of His mouth came a sharp double-edged sword.” Even in the heavens, Jesus still uses the Sword of the Spirit to deliver justice. The Word of God is powerful enough to speak the universe into existence and to enact divine judgment on the wicked and evil in the world.
So where do we get this sword, and how do we learn how to use it? Psalm 119:11 gives us the answer – “I have hidden your Word in my heart,” Simply put, we memorize Scripture. Every verse, every passage, every promise, and every truth adds to the power of your Sword. And the more you study the Word and meditate on it, the more adept you will be at using it. Is there a particular area of weakness or stronghold where Satan usually attacks? Look for Scripture that addresses that area. Read the verses aloud, write them on notecards and place them in areas like the kitchen, your desk, your bathroom mirror, or bedside table. Get a journal and write the verses out, look up the words, consider how this verse applies to your life – these are all excellent “drills” to help you grow in knowledge and strength in the Word of the Lord. The final step though is to submit to and obey the Word hidden in your heart.
Consider this, when Satan launches an attack against you, and all you know is John 3:16, (which is an awesome verse to know), you are trying to defeat the enemy with a pocketknife. But if you have been reading, studying, meditating, and memorizing Scripture, when you reach into your heart where that Word has been stored and grab hold of those verses, you are going to pull out a SWORD that will send your enemy reeling and scrambling. Beloved, That’s how you do battle with the enemy of your soul!
