In the wars of America’s past, famous battles have occurred at critical locations. Saratoga, Gettysburg, Normandy—victory or defeat at these critical sites had a substantial effect on the course of each war and its eventual outcome.

As we have seen, God’s objective is our righteousness and holiness. But you and I are continually engaged in conflict with our opponents: the world, the flesh, and the forces of Satan. This is not mere metaphorical babble; it is reality. We face both outright assault as well as subtle pressure to yield.

In this ongoing war, your mind is the strategic battlefield. The thoughts you think will lead you either to spiritual victory or defeat. How you think is having a substantial effect, not only on your present spiritual condition, but ultimately, on the course of your life. In this invisible war, the mind truly matters!

I. Recruit Evaluation

Which of these emotions or reactions are regularly problematic for you: A critical spirit/anger/resentment, Anxiety/worry/fear, Discouragement/self-pity/depression, Self-condemnation/guilt, Envy/jealousy, Complaining/discontentment/covetousness, Self-centeredness/ ambition/desire to control.

II. Basic Training

The Word of God has much to say about our minds. When we become new creations in Christ (2 Corinthians 5:17), God wants us to begin thinking in a new way. As we study the following verses, the Lord will instruct us how to take a key step toward spiritual victory by thinking Biblically!

1. Read Ephesians 4:17–24 and answer these questions. What command is given to us (v. 17)? What are the results of an unbeliever’s thinking habits (vv. 18, 19)? How are we to become different (v. 23)? What will be the result of being renewed in our minds (v. 24)?

2. Now read Romans 12:2. What are we instructed to do? How will we be transformed? What will be the result of a renewed mind? Why is it so important to have a renewed mind?

Prior to salvation, you had a “carnal mind” that had no inclination to please God (Romans 8:7). But now, as a believer, you have a new nature that is both willing and able to love and obey God (Romans 7:22, 23). Your “mind/heart” organ is the control center of your being. In fact, your mind directs your will. And since God has granted you a free will to choose to obey or disobey Him, your mind needs to be filled with thoughts of how to love and please God.

3. Read the following verses and explain why the “mind/heart” is so critical: Proverbs 4:23; Proverbs 23:7; Matthew 12:33–35.

You must fully grasp the fact that your thoughts and continual thought patterns are determining your character and choices. What goes on in your mind is influencing your will, your words, your attitudes, and your actions. And it affects what you do with your emotions. This is why your mind is a strategic battlefield where spiritual victory or defeat occurs.

4. Mind renewal involves breaking “old life” thought patterns and changing the way we think. What are some of these “thinking habits” that hang on from our old life? See 1 Corinthians 3:3; 1 Corinthians 3:19, 20; and 2 Timothy 1:7.

5. What emotion is addressed in each of these verses, and what Biblical thoughts will lead you to properly handle it? Psalm 56:3, 4; Romans 8:33, 34; Ephesians 4:31, 32; 1 Peter 5:5, 6.

Rampant emotions, fleshly thinking, ungodly attitudes. It is a cycle that can lead a believer to a life of turmoil and spiritual failure. But God, by His Word and His Spirit, can free us from this defeating cycle and cause us to be women who experience spiritual victory in the battles of life.

So then, is this simply a “positive thinking” philosophy? No. We cannot bring about real, permanent change of character merely by positive thinking. First of all, we are to think Biblically, not positively. We are not filling our minds with good thoughts about ourselves but thoughts about God and His will. Second, the Word itself is a Book of inherent power because it has proceeded from God (1 Thessalonians 2:13; Hebrews 4:12). The words are words that can change us.

6. What personal benefits did the psalmist gain as he filled his life with Scripture? See Psalm 119:6, 28, 45, 49, 98, 165.

In addition to the power of the Word dwelling richly in us, we have the power of the Spirit living within us. Working together, these two powerful agents accomplish something truly amazing in us: a changed life! This is the glorious advantage Christians have over unbelievers.

7. What do these verses teach you about God’s power and its result in your life? 2 Corinthians 3:17, 18; Ephesians 1:19, 20; Ephesians 3:20; Philippians 2:13.

Recall that Romans 12:2 states, “Be ye transformed by the renewing of your mind.” We are not commanded to transform ourselves but to permit the transformation to take place as our minds are renewed by the Word. Our job is to absorb God’s Word and yield to the Spirit’s leading (Galatians 5:16). Indeed, the Spirit desires to lead us in our thinking and in the meditations of our hearts.

The more we submit ourselves to His influence through the Word and prayer, the more we will begin to think, speak, and act as Christ did. Our fleshly thoughts and reactions will be replaced by His God-pleasing mind-set and His godly responses (1 Corinthians 2:16; Philippians 2:5). As the Word fills our minds and the Lord possesses our hearts, we will walk in the righteousness and holiness God desires.

III. Deployment

1. Who’s controlling your mind? Though we may not be aware of it, we are being pressured to conform to this world. Can you think of a motto, advertising slogan, or song that might plant unbiblical thinking in people’s minds?

2. Carnal thinking, vain imaginations, a spirit of fear—as believers, we must put off the mind-set of the old life. What will you do to break down these ungodly thought patterns?

3. Perhaps you’re wondering, “Is it possible to think Biblical thoughts throughout a busy day of duties and distractions?” We can take steps that will help us be Scripturally minded. List some ways of directing your thoughts toward the Lord and His Word.

4. What kind of personal prayer requests can you add to your prayer list that deal with this area of Biblical thinking?

5. Refer to section I again. What problematic emotions persistently surface for you? How can you begin to rein in these emotions by Biblical thinking?

IV. Debriefing

When you think of your life before and after salvation, would you say that you have changed or have basically remained the same?

Are you taking in Scripture on a consistent basis?

Would you say that, in general, you are working to bring your thought-life into obedience to Christ?

Do you more often emotionally react or calmly respond?

Do you endeavor to think Biblically in times of frustration, fear, or friction?

Do you understand that the Word and the indwelling Spirit are God’s powerful provisions to transform you? Do you earnestly desire to be changed?

V. Battlefield Report

The field of battle is your mind. Attacks will come—suddenly and sometimes forcefully. They may come from the weapons of the world, the bombardments of the flesh, or the subtle ambushes of our adversary, Satan. How successful have you been in resisting the assault? Do you find that your defense fails rather quickly?

Your first strong line of defense is Biblical thinking. It can subdue destructive emotions. It can detect the Devil’s deceitful devices. It can take into captivity the thoughts that lead to defeat. As you become entrenched in Scripture and empowered by the Spirit, attacks will be rebuffed. The enemy will gain no foothold, and victory can be secured. Yes, your mind can be the scene of many victorious conquests!
