Bible Study Lesson: WHAT’S ON YOUR MIND?
Theme: Winning the Battle in Your Mind
Key Scripture: Philippians 4:8 “Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report… think on these things.”
Supporting Scriptures: Proverbs 23:7; Romans 12:2; 2 Corinthians 10:5; Isaiah 26:3
Introduction: What’s on Your Mind?
It’s a simple question we ask people all the time:
“What’s on your mind?”
Usually we ask it when we can tell somebody is thinking about something.
They may not have said a word, but something about them tells us there’s something on their mind.
And the truth is, all of us have something on our minds.
We’re thinking about our families.
We’re thinking about our finances.
We’re thinking about our jobs.
We’re thinking about our health.
We’re thinking about something somebody said.
We’re thinking about what happened yesterday.
And sometimes we’re thinking about what might happen tomorrow.
The question isn’t whether you’re thinking.
The question is: What’s on your mind?
Because whatever stays on your mind long enough can eventually affect your attitude, your emotions, your decisions, and even your faith.
That’s why Paul says in Philippians 4:8:
“Think on these things.”
Paul understood that we have to be intentional about what we allow to occupy our minds.
Because every thought that comes into your mind—
doesn’t deserve to stay on your mind.
So tonight, as we study God’s Word, I want you to keep asking yourself one simple question:
What’s on my mind?
- YOU CAN’T STOP EVERY THOUGHT FROM COMING
2 Corinthians 10:5 — “…bringing into captivity every thought to the obedience of Christ.”
Sometimes we condemn ourselves because a bad, fearful, angry, or negative thought entered our minds.
But there is a difference between a thought entering your mind and you entertaining the thought.
You cannot always control what knocks on your door.
But you can control what you invite inside.
A thought may say:
“You’re not going to make it.”
“Nobody cares about you.”
“Things will never get better.”
“You might as well give up.”
But just because you thought it doesn’t mean you have to believe it.
Paul says we must bring our thoughts into captivity.
That means we don’t allow every thought to run freely through our minds.
We stop and ask:
Is this thought consistent with what God has said?
Practical Example
Suppose somebody walks past you without speaking.
Immediately you think:
“They must have a problem with me.”
Now your mind starts building a whole story.
“They don’t like me.”
“They’ve been acting funny.”
“I knew something was wrong.”
And they may have simply not seen you!
One thought created an entire situation that never existed.
Discussion
- What’s the difference between having a thought and entertaining a thought?
- Have you ever discovered that something you were worried about was mostly created by your own assumptions?
- How can we learn to stop a negative thought before it becomes a negative attitude?
Key Thought
You don’t have to believe everything you think.
- WHAT YOU THINK ABOUT WILL AFFECT HOW YOU FEEL
Proverbs 23:7 — “For as he thinketh in his heart, so is he.”
Thoughts have consequences.
Think about something that made you angry yesterday, and you can become angry all over again today.
Think about something painful, and emotions can return even though nothing is happening at that moment.
Think continually about everything that could go wrong, and worry begins to grow.
But the opposite can also happen.
Think about God’s goodness.
Think about prayers He answered.
Think about doors He opened.
Think about situations He brought you through.
And suddenly something begins to change.
Your thoughts can affect your emotions.
This is why we must be careful about repeatedly rehearsing painful experiences.
There’s a difference between remembering what happened and living in what happened.
Some people have physically left a situation that their mind keeps returning to.
God brought you out—
but your thoughts keep taking you back.
Discussion
- Why do negative thoughts sometimes seem easier to remember than positive ones?
- Can constantly replaying an offense keep us emotionally connected to something God wants us to move beyond?
- What are some healthy ways Christians can redirect their thinking?
Key Thought
Don’t allow yesterday to keep occupying today’s mind.
- YOUR MIND HAS TO BE RENEWED
Romans 12:2 — “And be not conformed to this world: but be ye transformed by the renewing of your mind…”
Notice Paul doesn’t just say we need a new life.
He says we need a renewed mind.
Because you can change your location without changing your thinking.
You can change relationships without changing your thinking.
You can get a new job without changing your thinking.
You can even come to church every Sunday without changing your thinking.
God doesn’t only want to change where you are.
God wants to change how you think.
Some thoughts come from years of experiences:
“I’ve always been this way.”
“Nobody in my family ever did that.”
“I could never accomplish that.”
“Nothing good ever happens for me.”
But when Christ enters our lives, His Word begins challenging old ways of thinking.
Instead of:
“I can’t.”
We remember:
“I can do all things through Christ which strengtheneth me.”
Instead of:
“I’m by myself.”
We remember:
“I will never leave thee, nor forsake thee.”
Instead of:
“There’s no way.”
We remember:
“With God all things are possible.”
Renewing your mind means learning to let God’s truth become louder than your old thinking.
Discussion
- What does it practically mean to “renew your mind”?
- Are there thought patterns we can carry for years without realizing they are unhealthy?
- Why is knowing Scripture important in changing how we think?
Key Thought
A changed life requires a changed mind.
- THINK ABOUT WHAT YOU’RE THINKING ABOUT
Now we arrive at Philippians 4:8.
Paul gives believers a filter for their thoughts:
Is it true?
Is it honest?
Is it just?
Is it pure?
Is it lovely?
Is it of good report?
Is there virtue in it?
Is there anything praiseworthy about it?
Then Paul says:
“Think on these things.”
In other words, don’t allow your mind to operate on autopilot.
Sometimes you need to stop yourself and ask:
“Why am I thinking about this?”
“Is this true—or am I assuming?”
“Is this helping me—or hurting me?”
“Is this bringing me closer to God—or pulling me away?”
“Is this something I need to address—or something I need to release?”
Philippians 4:8 does not mean Christians ignore reality.
It means we refuse to allow everything negative about reality to dominate our minds.
You can acknowledge the problem and still think about God’s promises.
You can acknowledge that you’re hurting and still believe healing is possible.
You can acknowledge that today is difficult and still believe:
Tomorrow can be different.
Group Exercise: Put the Thought Through the Filter
Take a common thought:
“Everything is going wrong.”
Ask: Is everything really going wrong?
Probably not.
Instead, try:
“I’m going through something difficult, but God has brought me through difficult things before.”
That’s not denial.
That’s disciplined thinking.
- RIGHT THINKING PRODUCES PEACE
Isaiah 26:3 — “Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee.”
Notice the connection:
Mind → God → Trust → Peace.
Sometimes we’re asking God for peace while continually feeding our minds the very things that disturb our peace.
You pray for peace—
then spend the next hour worrying.
You ask God to handle it—
then mentally pick it back up.
You tell God, “I trust You”—
then spend all night imagining everything that could go wrong.
Isaiah says there is peace available when our minds are stayed on God.
That doesn’t mean the trouble disappears.
It means the trouble doesn’t have to control what’s happening inside of you.
The storm can be around you without the storm getting inside you.
Discussion
- What’s the difference between having peace and having no problems?
- What things compete for control of our thoughts today?
- What practical habits can help us keep our minds focused on God?
Practical Ways to Guard Your Thinking
- Start your day with God’s Word before filling your mind with everything else.
- Question negative assumptions. Ask, “Do I actually know this is true?”
- Stop rehearsing offenses. Forgiveness also involves what you choose to keep replaying.
- Replace wrong thoughts with Scripture. Give your mind something better to think about.
- Be careful what continually enters your mind. What you watch, hear, read, and discuss can influence your thinking.
- Practice gratitude. Remembering what God has done helps change what dominates your attention.
Closing: Change the Channel
Sometimes when you’re watching television, something comes on that you don’t want to watch.
You don’t sit there arguing with the television.
You don’t spend thirty minutes asking why the program came on.
You change the channel.
There are times when we need to learn how to change the channel in our minds.
When fear comes on—
Change the channel.
When bitterness starts playing—
Change the channel.
When your mind starts replaying what somebody did—
Change the channel.
When the enemy starts telling you that you’re not going to make it—
Change the channel.
And tune your mind into what God has said.
God says:
“I’ll never leave you.”
God says:
“I’ll supply your needs.”
God says:
“No weapon formed against you shall prosper.”
God says:
“Weeping may endure for a night, but joy cometh in the morning.”
So when somebody asks:
“What’s on your mind?”
I want to be able to say:
I’m thinking about what God said.
I’m thinking about His goodness.
I’m thinking about His promises.
I’m thinking about how He brought me through before.
I’m thinking about the fact that if He did it before—
He can do it again.
So this week, don’t just watch what you say.
Don’t just watch what you do.
Watch what’s on your mind.
Because you may not be able to control every thought that enters your mind—
but through Christ, you can decide which thoughts get to stay.
“Whatsoever things are true… honest… just… pure… lovely… of good report… think on these things.”
Final Discussion Question
What’s been taking up the most space in your mind lately—and does it deserve to be there?
