“Take up the sword of the Spirit, which is the Word of God,” (Ephesians 6:17).
Did you notice that 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 says “For the Word of God is living and active, sharper than any double edged sword.” Revelation 1:12-16 describes the God-Man, Jesus Christ as He appears in John’s vision; verse 16 tells us “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.
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 weight and length and strength 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.
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 to get away. That’s how the child of God does battle with the enemy of our soul!
