The Armor of God

Bible Study Notes | September 30th, 2026

Main Scripture: Ephesians 6:10–18

“Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.”

Introduction: You’re in a Fight

Paul closes the book of Ephesians by telling believers:

“Finally, my brethren, be strong in the Lord, and in the power of his might.”

Paul doesn’t tell them to be strong in themselves.

He says:

“Be strong in the Lord.”

That’s important because there are some battles that human strength cannot win.

There are some things you can’t think your way through.

You can’t argue your way through them.

You can’t buy your way out of them.

You can’t fight them with your personality, position, education, or influence.

Because Paul tells us in verse 12:

“For we wrestle not against flesh and blood…”

In other words:

Be careful that you don’t fight the wrong enemy.

Sometimes we make people the enemy.

We say:

“My problem is my coworker.”

“My problem is my spouse.”

“My problem is somebody at church.”

“My problem is my supervisor.”

“My problem is my family.”

But Paul says there is something happening behind what you can see.

The believer is engaged in spiritual warfare.

The enemy attacks our faith.

He attacks our minds.

He attacks families.

He attacks relationships.

He attacks unity.

He attacks our peace.

He attacks our confidence in God.

And because the battle is spiritual, we need spiritual equipment.

Paul uses the picture of a soldier getting dressed for battle.

Every piece has a purpose.

Nothing is accidental.

Nothing is unnecessary.

And Paul doesn’t say:

“Put on the armor.”

He says:

“PUT ON THE WHOLE ARMOR.”

Because you don’t want to go into battle with part of you protected and another part exposed.

Discussion Question

What changes when we realize that the person causing us difficulty may not actually be the real enemy?

THE BELT OF TRUTH

Ephesians 6:14

“Stand therefore, having your loins girt about with truth…”

For the Roman soldier, the belt helped secure his clothing and equipment so that he could move freely in battle.

Paul begins with truth.

Why?

Because truth holds everything together.

And one of Satan’s oldest weapons is a lie.

Go all the way back to Genesis.

The serpent’s strategy with Eve was to make her question what God had said:

“Yea, hath God said…?”

The enemy knows that if he can make you doubt what God said, he can begin changing what you believe.

And if he changes what you believe, eventually he can influence how you behave.

That’s why truth matters.

We live in a world where everybody has an opinion.

Social media has an opinion.

Culture has an opinion.

Your friends have opinions.

Your feelings have an opinion.

But the believer has to ask:

“WHAT DID GOD SAY?”

Because everything you feel isn’t necessarily true.

You may feel alone.

But God said:

“I will never leave thee, nor forsake thee.”

You may feel that your situation is hopeless.

But God’s Word teaches that nothing is too hard for Him.

You may feel that your past disqualifies you.

But Scripture teaches that if anyone is in Christ, that person is a new creation.

So when the enemy gives you a lie, you need enough truth to recognize it.

The belt of truth means:

I am going to build my life around what God says rather than what the enemy suggests.

Discussion Questions

What are some common lies the enemy uses against believers today?
How can knowing Scripture help us recognize when something we’re thinking or hearing isn’t true?

THE BREASTPLATE OF RIGHTEOUSNESS

Ephesians 6:14

“…and having on the breastplate of righteousness.”

The breastplate protected the soldier’s vital organs.

Most importantly, it protected the area around the heart.

Paul uses righteousness as the believer’s breastplate.

Our standing before God is not based on our own goodness; we are made righteous through Christ.

But because we belong to Christ, our lives should reflect Him.

The enemy loves compromised areas.

If there is unforgiveness in your heart, he will work on it.

If there is bitterness, he will work on it.

If there is jealousy, pride, lust, dishonesty, or resentment, the enemy will look for ways to exploit it.

That’s why Proverbs 4:23 says:

“Keep thy heart with all diligence; for out of it are the issues of life.”

You have to guard your heart.

Everybody shouldn’t have access to your heart.

Everything shouldn’t be allowed to live in your heart.

And everything shouldn’t be allowed to grow in your heart.

Sometimes we ask God to change the people around us when we need to ask:

“Lord, what’s happening inside me?”

Righteous living doesn’t mean perfection.

It means when God reveals something wrong, we deal with it instead of defending it.

We confess it.

We repent.

We change direction.

Because you don’t want to give the enemy an unprotected place to attack.

Discussion Questions

Why is protecting our hearts so important in spiritual warfare?
What are some attitudes that can quietly get into our hearts and affect our relationship with God and others?

FEET PREPARED WITH THE GOSPEL OF PEACE

Ephesians 6:15

“And your feet shod with the preparation of the gospel of peace.”

A soldier could have excellent armor and a powerful weapon, but if he couldn’t keep his footing, he was vulnerable.

He needed something underneath him that would allow him to stand.

Paul says the Gospel provides that foundation.

The Gospel reminds us:

Jesus came.

Jesus died for our sins.

Jesus was buried.

Jesus rose again.

Through Christ we have been reconciled to God.

That gives the believer peace.

But notice the contrast.

Paul is talking about warfare, yet he puts peace on our feet.

Because spiritual strength doesn’t always look like shouting and fighting.

Sometimes spiritual strength is being able to remain peaceful when everything around you is chaotic.

The enemy wants you reacting emotionally to everything.

He wants every phone call to shake you.

Every rumor to upset you.

Every disagreement to disturb you.

Every unexpected situation to make you panic.

But the Gospel gives us something solid to stand on.

Peace doesn’t mean nothing is wrong.

Peace means what’s wrong doesn’t control you.

You can have trouble around you without allowing trouble to take over inside you.

Jesus demonstrated this in the storm.

The disciples were panicking.

The storm was raging.

But Jesus was asleep.

Same boat.

Same storm.

Different response.

That’s what peace can do.

Discussion Questions

What is the difference between having peace and having no problems?
What practical things can we do to protect our peace when circumstances around us become chaotic?

THE SHIELD OF FAITH

Ephesians 6:16

“Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.”

Paul says the enemy has fiery darts.

Those darts can come in many forms:

Fear.

Doubt.

Temptation.

Discouragement.

Disappointment.

Accusation.

Negative thoughts.

Questions about whether God will really come through.

Notice Paul doesn’t say the enemy won’t shoot.

He says:

You have something to stop what he’s shooting.

That’s the shield of faith.

Faith doesn’t mean:

“I know exactly what’s going to happen.”

Faith means:

“Whatever happens, I trust God.”

Faith doesn’t say:

“I understand everything God is doing.”

Faith says:

“I trust Him even when I don’t understand Him.”

Abraham didn’t know every detail.

But he trusted God.

Moses didn’t know how the Red Sea would open.

But he had to trust God.

The three Hebrew boys didn’t know whether God would keep them out of the furnace.

They said:

“Our God…is able to deliver us.”

But then they essentially said:

“And even if He doesn’t, we’re still not bowing.”

That’s faith.

Sometimes faith isn’t believing God will do exactly what you want.

Sometimes faith is saying:

“God, however You choose to handle this, I’m still trusting You.”

And when the fiery darts start flying—

raise your shield.

Discussion Questions

What are some “fiery darts” you have seen attack people’s faith?
How can we strengthen our faith before difficult seasons come rather than waiting until we’re already in the battle?

THE HELMET OF SALVATION

Ephesians 6:17

“And take the helmet of salvation…”

The helmet protects the head.

And spiritually, some of our greatest battles happen in our minds.

You can be sitting in church and fighting something in your mind.

You can be smiling at work and fighting something in your mind.

You can be surrounded by family and fighting something in your mind.

The enemy understands that if he can influence your thinking, he can influence your living.

That’s why Scripture repeatedly addresses the mind.

Romans 12:2 talks about being transformed by the renewing of your mind.

Philippians 4:8 tells us to think on things that are true, honest, just, pure, lovely, and of good report.

The helmet of salvation reminds us of our identity.

When the enemy says:

“God doesn’t love you.”

The helmet says:

“God loved me enough to send His Son.”

When the enemy says:

“Look at your past.”

The helmet says:

“I’ve been forgiven.”

When the enemy says:

“You’ll never change.”

The helmet says:

“I am being transformed through Christ.”

When condemnation comes, remember:

I belong to Jesus.

We have to become intentional about what we allow to occupy our thoughts.

You can’t stop every thought from arriving.

But you don’t have to give every thought somewhere to live.

Discussion Questions

Why do you think the mind is such an important battlefield for Christians?
How can we tell the difference between conviction from God and condemnation that simply keeps us trapped in guilt?

THE SWORD OF THE SPIRIT — THE WORD OF GOD

Ephesians 6:17

“…and the sword of the Spirit, which is the word of God.”

Now Paul gives the soldier a weapon.

The other pieces primarily protect.

But the sword allows the soldier to respond.

And notice what God places in our hands:

HIS WORD.

This is why Bible study is important.

This is why Scripture memory is important.

This is why reading your Bible beyond Sunday morning is important.

Because when the battle comes, you need something inside you that you can use.

Jesus demonstrated this in Matthew 4 when Satan tempted Him in the wilderness.

Every time Satan came with temptation, Jesus responded:

“It is written.”

Satan came again.

“It is written.”

Satan tried another temptation.

“It is written.”

Jesus didn’t debate Satan.

He answered him with Scripture.

And that’s a lesson for us.

When fear says:

“You’re alone.”

What does the Word say?

When worry says:

“You’re not going to make it.”

What does the Word say?

When temptation says:

“It won’t hurt anything.”

What does the Word say?

When the enemy says:

“God has forgotten you.”

What does the Word say?

You cannot effectively use a sword you never pick up.

And you can’t quote a Word you’ve never learned.

The time to learn how to use your weapon is before the battle gets intense.

Discussion Questions

Why is it important to know Scripture for ourselves rather than depending only on what we hear preached or taught?
What Scriptures have helped you personally during difficult seasons?

PRAYER — STAYING CONNECTED TO GOD

Ephesians 6:18

“Praying always with all prayer and supplication in the Spirit…”

Paul has described the armor, and then immediately says:

Pray.

Prayer keeps the soldier connected to the One directing the battle.

Notice the words:

“Praying always.”

Not only when something goes wrong.

Not only when the doctor gives bad news.

Not only when money gets tight.

Not only when your family has trouble.

Not only when you need God to fix something.

Always.

Prayer should not merely be our emergency response.

Prayer should be our lifestyle.

Sometimes we treat prayer like calling 911.

We only call when there’s an emergency.

But God wants relationship.

Prayer is where we seek direction.

Prayer is where we receive strength.

Prayer is where we confess.

Prayer is where we listen.

Prayer is where we intercede for other people.

And prayer reminds us:

I don’t have to fight this by myself.

That’s why Paul began this entire section by saying:

“Be strong in the Lord, and in the power of his might.”

Our strength isn’t enough.

His is.

Discussion Questions

What is the difference between having a prayer life and only praying when something goes wrong?
What are some practical ways we can become more consistent in prayer?

THE COMMAND THAT HOLDS EVERYTHING TOGETHER: STAND

Look at how many times Paul returns to this idea.

Ephesians 6:11:

“That ye may be able to stand.”

Verse 13:

“Having done all, to stand.”

Verse 14:

“Stand therefore…”

God doesn’t tell you to chase the devil.

He tells you:

STAND.

Sometimes we define victory as everything immediately changing.

But maybe victory looks different.

Maybe the marriage went through a difficult season—
