Good morning. It’s a joy to be with you again as we continue our series, The War for Your Soul: Defending the Faith. We are currently in a spiritual warfare series where we’re learning to stand firm in Christ and fight the battles we can’t always see—but feel. Remember, we're all on this journey together.

Before we get started, let’s begin with a word of prayer.

Heavenly Father, we come to You today hungry for Your truth. We know battles are raging in our minds and hearts—battles we can’t win without You. As we open Your Word, would You open our eyes? Would You tear down the lies we’ve believed and replace them with the truth that sets us free? We ask for clarity, conviction, and courage. In Jesus’ name, amen.

Let me ask you something: Have you ever found yourself stuck in a pattern of thinking that you *know* isn’t right—but you can’t seem to break free? Maybe it’s fear that keeps whispering, “You’re not safe.” Perhaps shame says, “You’ll never be enough.” Or maybe it’s bitterness, pride, or addiction that keeps circling back over and over.

Today’s message matters because the battlefield of spiritual warfare isn’t always out there—it’s right here, in our minds and hearts. The war for your soul is often fought in the hidden places of your mind and heart. And the enemy’s favorite tactic? Lies. If he can get you to believe a lie, he can build a stronghold in your life.

But there is good news: **Truth tears down what lies built up.**

That’s the phrase I want you to carry with you throughout this message—and into your week.

**Truth tears down what lies built up.**

Let’s see how the Word of God speaks directly to this battle.

Now, let’s see what God’s Word actually says about this battle for the mind. Because if we’re going to fight back, it's crucial that we understand the enemy’s tactics—and the powerful weapons God has placed in our hands.

What is a Stronghold

Let's begin by looking closely at our key passage:

For though we walk in the flesh, we are not waging war according to the flesh. For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds. We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ,

A "stronghold" in this context refers to more than just a bad habit—it is a deeply entrenched way of thinking that stands opposed to God's truth. In Paul's imagery, strongholds are mental fortresses of lies—arguments, pretensions, and false beliefs that exalt themselves against God's knowledge.

These may include:

- False beliefs about God ("He doesn't care about me.”)

- Lies about yourself ("I'll never change.”)

- Cultural philosophies that oppose biblical truth ("Live your truth.”)

Strongholds are not just beliefs but mental fortifications built in the mind. They're strong not because they're true but because we've lived with them for so long that they feel true. But Paul says we are to demolish them—not negotiate with them, not tolerate them, but tear them down.

And how? Not with fleshly tactics but with the powerful weapons of God—truth, righteousness, faith, the Word of God, and prayer (Ephesians 6:10–18). These are not just tools but powerful instruments that can bring about the demolition of strongholds.

Why? Because:

**Truth tears down what lies built up.**

The Minds Role

Paul writes in Romans 12:2:

Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.

This verse shows us that spiritual warfare is not won through emotional hype or physical effort—it is won through transformation, and that transformation happens at the level of the mind.

Let's unpack that. The phrase "do not be conformed to this world" is literally "do not be conformed to this age." Paul is saying: Don't let the patterns and thinking of this fallen world shape your mind. Don't let the world squeeze you into its mold.

Instead, he says, "Be transformed by the renewing of your mind."

Paul writes this in what we refer to as a passive form, "be transformed." That means that we are passive in the action of the transformation. But what exactly does that mean? We are passive in the work of the transformation because it is all a work of God in us.

Paul, in his choice of the verb form, also states that this is a continuous, ongoing reality. We must engage in it daily, renewing our minds through the Word, the Spirit, and obedience. This daily renewal is not a burden but a source of inspiration and motivation in our spiritual journey.

What does "renewing the mind" mean?

It's not just learning new facts. It's allowing the Holy Spirit to *reprogram* our thinking with God's truth. It's the reversal of the depraved, darkened thinking described in Romans 1:28. It's a moral and spiritual recalibration that enables us to see and approve what God calls good.

We need to start thinking like people in the age to come, which means we need to stop thinking like people of the present.

So why is the mind such a battleground in spiritual warfare?

Because your thoughts shape your beliefs, your beliefs shape your actions, and your actions shape your life.

That's why Satan targets the mind. He doesn't need to overpower you. He needs to deceive you. And deception is his oldest tactic (Genesis 3).

But what does the truth do?

**Truth tears down what lies built up.**

Common Strongholds

Let's delve into the concept of 'strongholds'-these are deeply rooted beliefs or thought patterns that can hold us captive and hinder our spiritual growth. As Christians, we often carry these strongholds daily. But more importantly, I want us to hear what God says about these lies that Satan is whispering to us, and how we can combat them with biblical truths.

- **Fear** – The lie: “I’m not safe unless I’m in control.”

> *2 Timothy 1:7 – “God gave us a spirit not of fear but of power and love and self-control.”*

- **Shame** – The lie: “I am my worst enemy. I can’t be forgiven.”

> *Romans 8:1 – “There is therefore now no condemnation for those who are in Christ Jesus.”*

- **Bitterness** – The lie: “Holding onto this pain protects me.”

> *Ephesians 4:31–32 – “Let all bitterness and wrath… be put away from you… Be kind to one another, tenderhearted, forgiving one another.”*

- **Addiction** – The lie: “I need this to cope. I can’t live without it.”

> *1 Corinthians 10:13 – “God is faithful… He will also provide the way of escape, that you may be able to endure it.”*

- **Pride** – The lie: “I’ve got this. I don’t need help.”

> *Proverbs 16:18 – “Pride goes before destruction, and a haughty spirit before a fall.”*

Each of these strongholds is built on a lie. Although they may feel real, they are not grounded in the truth of God’s Word.

But when we allow the Word of God to transform our hearts and minds, we will begin to live the truth that:

**Truth tears down what lies built up.**

The Power of The Word

Jesus said in **John 8:31–32**:

So Jesus said to the Jews who had believed him, “If you abide in my word, you are truly my disciples, and you will know the truth, and the truth will set you free.”

These words are among the most quoted in Scripture and the most misunderstood. Jesus is not talking about abstract facts or philosophical principles. He is talking about *Himself*. The truth that sets us free is the truth revealed in and through the Person of Jesus Christ—His teaching, His character, His redemptive work. He is, after all, “the way, the truth, and the life” (John 14:6).

But notice something crucial: this promise of freedom is not for everyone. It is for those who abide in His Word. The word “abide” means to remain, dwell, and live. This is not about a passing interest in Jesus or a temporary emotional experience. This is about a life rooted in the Word of Christ.

John’s Gospel gives us sobering context. The people Jesus spoke to in John 8 had “believed” in Him—at least superficially (v. 30). But Jesus knew that many of them would not remain. In fact, just a few verses later, He calls them children of the devil (v. 44) and exposes the falseness of their faith. Why? Because they did not abide in His Word. They did not continue with Him when it became costly.

True discipleship is marked by perseverance in the truth—not just a profession of faith but a pattern of obedience. And when we abide in Jesus’ Word, two things happen:

First, we know the truth. Not just intellectually but experientially. We grow in our understanding of who God is, who we are, and what freedom in Christ truly looks like. This knowing changes us.

Second, we are set free—free from the lies that once enslaved us, free from the grip of sin, free from guilt and shame. The truth doesn’t just educate—it liberates. But that freedom only comes by walking in the truth, not just hearing it.

The Jewish listeners in John 8 didn’t realize they were in bondage. They rested in religious heritage, tradition, and national pride—but not in Christ. Many today do the same. But freedom doesn’t come from religion, morality, or self-help. It comes from the Word—and the Word made flesh.

This is why Scripture is essential in tearing down strongholds. It exposes lies and replaces them with truth.

• When the enemy says: “You’ll never be free,” Jesus says: “Whom the Son sets free is free indeed” (John 8:36).

• When he says: “You’re not good enough,” the Word says: “You are God’s workmanship, created in Christ Jesus” (Ephesians 2:10).

• When he whispers: “You can’t change,” Jesus declares: “If anyone is in Christ, he is a new creation” (2 Corinthians 5:17).

You don’t defeat lies with effort or willpower—you defeat them with truth. And that truth is found in the abiding Word of God.

So never forget that: Truth tears down what lies built up.

How Do I Live This Out?

We need to do some things to live out the lessons in this sermon.

First, we need to identify the strongholds. These deeply ingrained patterns of thinking or behaving that hinder our spiritual growth and keep us from experiencing God's best for our lives.

Identify the Strongholds

This starts with honest self-examination. What lie have you believed? What behavior or thought pattern keeps showing up and pulling you away from God's best?

It could be:

- A lie like "I'm not lovable" that began in childhood.

- A thought like "I'll never change" after years of struggle with sin.

- A mindset like "I need to stay busy to have worth" is rooted in performance.

We need to ask God to reveal the lies we believe. Pray like David in Psalm 139:23–24.

Search me, O God, and know my heart! Try me and know my thoughts! And see if there be any grievous way in me, and lead me in the way everlasting!

We cannot defeat what we refuse to name. Until the lie is exposed, the stronghold will remain.

Next, we need to replace the lie with the truth.

Replace the lie with the truth.

This is not about positive thinking or surface-level affirmations. This is about real, Spirit-empowered replacement. Once you identify the lie, go to Scripture and ask: What does God say? Scripture guides this process, providing us with the truth that can replace the lies we've believed.

Make a list. Write down the lie, then directly beneath it, write the truth.

For instance, you may write down the lie: "I'll never be free from this addiction."

Then right below that you need to write 2 Corinthians 3:17: "Where the Spirit of the Lord is, there is freedom." (2 Corinthians 3:17)

Then, you need to speak that truth over your life—daily, out loud, in your journal, on sticky notes on your mirror. The more you repeat the truth, the more it begins to renew your mind.

This isn't magic. It's spiritual transformation through consistent surrender.

Take Every Thought Captive

Paul didn't say, "Ignore the thought." He said to take it *captive*. That means stopping the lie midstream and examining it in light of Scripture.

Philippians 4:8 says:

Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things.

You're not a victim of your thoughts. With the help of the Holy Spirit, you can take control of them.

When a thought arises that fuels fear, shame, bitterness, or pride—pause and ask yourself:

- Is this true?

- Does this reflect God's character?

- Would Jesus say this to me?

If not, reject it and replace it.

Abide in the Word

Next, we need to abide by the Word of God.

Jesus said, "If you abide in my word… you will know the truth, and the truth will set you free." (John 8:31–32)

Freedom is not found in occasional Bible reading. It's found in *abiding*—dwelling, remaining, soaking in God's Word.

Let Scripture rewire your mind and reshape your identity. Make time each day to read, meditate, and memorize. The goal is not just information but transformation.

Walk with Community

Finally, we need to walk with the people of God, the Church.

Strongholds grow in isolation. But healing and breakthroughs happen in the community. The support and connection found in the Church are vital for our spiritual growth and healing, reminding us that we are not alone in our journey.

Find people who will speak truth into your life, gently but firmly call out lies, and remind you of who you are in Christ.

James 5:16 says:

Therefore, confess your sins to one another and pray for one another, that you may be healed. The prayer of a righteous person has great power as it is working.

Healing comes when we bring what's hidden into the light. That's where freedom begins.

Lean daily on the fact that: "Truth tears down what lies built up." When embraced and lived out, this truth has the power to transform our lives, inspiring us to continue our spiritual growth and healing journey.

So What?

So what? So what does this message mean when Monday comes, and the enemy starts whispering again?

It's not just you. The battle you feel is real, and it’s not a sign of weakness. It’s a sign that you're on the front line, ready to fight. You’re not alone in this.

Those recurring thoughts that have held you back? They don’t have to win anymore. You’ve been given the power to demolish them, not in your strength but in Christ’s. You are capable of overcoming them.

It means you can stop living like a victim of your past. Yes, the wounds are real. But they are not permanent. Your identity is not found in what happened to you. Your identity is found in who Jesus says you are.

It means that when your kids, spouse, or friends struggle with lies, you have something to offer: the truth. You become a warrior for them, too—fighting for your freedom and theirs.

Whether you’ve been walking with Jesus for decades or you’re just starting out, you’re not alone in this battle. You have a community, a family, and most importantly, Christ fighting with you. His Spirit dwells in you. His Word arms you. You are part of something bigger.

Imagine what your life would look like if you truly lived free—free from the lies, the shame, the weight. How would it change your relationships? Your work? Your prayer life?

This is what’s on the other side of the stronghold—freedom, peace, clarity, confidence, joy. All of it is rooted in the truth of God’s Word.

Truth tears down what lies built up.

Are you ready to start tearing down those lies in your life? Let's take the first step together.

Tearing Down Strongholds

Let me tell you about a man I counseled some years ago. He had carried bitterness toward his father for decades. The man had left when he was young, and the wound had never healed. He didn’t realize it, but that pain had turned into a stronghold. It affected his marriage, parenting, and even his walk with God. We spent weeks reading Scripture together—looking at how God forgives, how Jesus bore our wounds, and how bitterness chains us to our past. Slowly, he began to forgive. It wasn’t easy—but it was holy. And when he finally released that pain, he said, “It’s like I can breathe again.” That’s what happens when truth enters in.

And listen, that can be your story, too.

Let me take you to one more place in Scripture—a moment when a prophet of God faced a mental stronghold so heavy that he wanted to die.

In 1 Kings 19, Elijah has just come off one of the greatest spiritual victories recorded in the Bible. He called down fire from heaven, confronted the prophets of Baal, and proved to the people that the Lord—He alone is God.

But in the next chapter, he receives a threat from Queen Jezebel. And this one message sends him spiraling. He runs into the wilderness, sits under a broom tree, and says, “It is enough; now, O Lord, take away my life.” (v. 4)

What the heck happened?

A stronghold of fear, hopelessness, and isolation overwhelmed him. Despite all that God had done, Elijah now believed a lie: “I’m alone, and I’m going to die.” And that lie took over his mind.

But God didn’t leave him there. He sent an angel to nourish him. He led him to a cave. And then He spoke—not in the fire or earthquake, but in a still small voice.

God reminded Elijah of the truth:

- He was not alone—there were 7,000 in Israel who had not bowed to Baal.

- He was still in God’s plan—God had more work for him to do.

- His life still had a purpose.

God tore down the lies Elijah believed and rebuilt him with truth.

Maybe today, like Elijah, you’ve been running. Perhaps fear has gripped your heart. Maybe exhaustion has clouded your thinking. Maybe you’re believing the enemy’s whisper: “You’re done. It’s hopeless.”

Please listen very clearly to me. No matter where you find yourself right now in life. God is not done with you. He’s still speaking. And He wants to meet you—not with condemnation, but with grace. His truth still stands.

Truth tears down what lies built up.

We are in a war. But it’s not a war we can see with our eyes. It’s a war of thoughts, beliefs, and spiritual influence. And the battlefield is your mind and heart.

But we don’t fight this war with fleshly weapons. We fight with divine ones. We fight with the power of prayer, the wisdom of Scripture, the strength of worship, and the truth of Jesus Christ. These are tools and pillars of our spiritual journey, connecting us to God Almighty.

You don’t have to live in defeat. You don’t have to keep circling the same mountain. You don’t have to pretend anymore. The truth is that God has given you the power through the Holy Spirit to break free. You are not a victim of circumstances, but a powerful force in your own life.

When you walk in truth—day by day, moment by moment—you will start to see walls come down. Old mindsets will be replaced with new ones, fear with courage, shame with grace, and bondage with peace. This is not just a battle but a journey towards a brighter, more hopeful future.

This is the power of God’s truth in your life.

So here’s the call:

What stronghold do you need to face today?

Is it fear?

Shame?

Bitterness?

Lust?

Pride?

Unforgiveness?

Whatever it is, it doesn’t have to stay. You can start tearing it down today—not by trying harder but by surrendering deeper. By choosing truth. By choosing to abide in the Word of Christ.

This week, take one stronghold. Just one. Ask the Lord to expose the lie, then go to Scripture and replace it with truth. Share it with someone you trust. Pray over it every day. Speak it until you believe it.

Start the demolition process—brick by brick—with the sword of the Spirit in your hand.

Don’t leave today inspired but unchanged. Leave today determined to fight back. You’re not alone. Jesus, the creator of the heavens and the earth, is with you. His Word is in you. And His Spirit empowers you.

So, I will say it one last time today:

**Truth tears down what lies built up.**

Let us pray,

Father, we are inspired by Your Word, which shines light in our darkest thoughts. We are Hopeful because of the truth that sets us free. Lord, we confess that we’ve believed lies—some for years—and we ask You now to break every stronghold. Renew our minds. Heal our hearts. And lead us in Your truth. In the mighty name of Jesus, we pray.

“May the God of hope fill you with all joy and peace in believing, so that by the power of the Holy Spirit you may abound in hope.”

Amen and Amen

Be blessed to be a blessing.
