Armor of God Bible Study:
Spiritual Protection Against the Devil and his Angels


When you study the Bible about the armor of God, you find some interesting observations.  The armor of God that Christians are to wear does not consist of anything physical.  The Bible tells us that Christians are engaged in spiritual warfare.  This is why we find much military language in the Bible.

1 Timothy 6.12:  “Fight the good fight of faith” 

2 Corinthians 10.5:  “For the weapons of our warfare are not carnal, but mighty in God” 

1 Peter 2.11:  “Abstain from fleshly lusts which war against the soul.” 


The military terminology in the New Testament tells us that Christians are warriors engaged in a spiritual battle.  The armor that we are to wear is not physical but spiritual.  With that in mind, let’s study the Bible and give some consideration to the armor of God found in Ephesians 6.10-17. 


Armor of God Bible Study:  The Strength We Have in God

Ephesians 6.10:  “Finally, my brethren, be strong in the Lord and in the power of His might.”


Let’s break this verse down.

  •     “My brethren…”  refers to Christians.  

If you go back to the beginning of the book, you will find that Paul is addressing “the saints who are in Ephesus and faithful in Christ Jesus”  (Eph. 1.1).  Paul is writing to the faithful members of the church in Ephesus, and he is writing about the church.  So you need to remember this when you read these words in Ephesians 6.

  • “My brethren, be strong...  

The Greek word translated as “strong” is the word “dunamoo.”  This word comes from the root word “Dunamas” from which we get our English word “dynamite.” 

But then it has the prefix, “en.”  When you put those two words together you have “Endunamoo.”  Literally, it means, “power that is on the inside.”  You are to be powerful on the inside.  You are to have an inner strength. 

  • “My brethren, be strong in the Lord...” 

You are to have this inner strength.  The source of that strength is the Lord.  You are strong because of your relationship with God through Christ.

  • “My brethren, be strong in the Lord, and in the power of His might.  

The word “power” translates a word that means “greatness”, and "might" is a word that means “ability”. 

Look at what we just read.  By inspiration, the apostle Paul writes to Christians saying that you need to have this internal strength that comes from your relationship with God.  It is the greatness of His ability that makes this inner strength possible.  Your inner strength does not come because of your own abilities but because of the greatness of God’s abilities.

What this verse is essentially saying is that you are reliant upon the strength and power of God for your spiritual survival.  Be strong with the strength and power of God. 

  • There is to be this inner strength that gets you through the day.
  • It is this inner strength that enables you to overcome temptation.
  • It is this inner strength that helps you through the difficult times in your life.
  • It is this inner strength that drives you to do what God wants you to do.

This inner strength comes from your relationship with God where you know that you can succeed spiritually because of the strength and ability of a God who is always with you.  That is how this passage begins.  The writer then explains about putting on the armor of God.


Three Reasons Why We Need the Armor of God

Ephesians 5.11:  “Put on the whole armor of God, that you may be able to stand against the wiles of the devil.”

You need the armor of God that you may have the ability to stand your ground against the wiles of the devil. 


1.  You Need the Armor of God because the Devil is the Enemy

Our enemy is the devil.  This is why Peter wrote the following in 1 Peter 5.8.

1 Peter 5.8:  “Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour.”


  • If you are a democrat, the republicans are not your enemies, and this administration is not your enemy.
  • If you are a republican, the democrats are nor your enemies.
  • If you are a Catholic, the protestants are not your enemy. 
  • If you believe in same-sex marriage, those who oppose it are not your enemy.

Your enemy and my enemy is the devil.  It is a spiritual warfare.  When you have those who have a different religious positions or who have a different moral standard than what the Bible says, it is the devil who is responsible.  They are yielding to the enemy, but the enemy himself is the devil.  You and I need to remember that or we become victim to him as well.

You are told three times in the book of John that Satan is the prince or ruler of this world  (John 12.31; 14.30; 16.11).  That is why you can read the following in James 4.4.

James 4.4:  “Adulterers and adulterouses, do you not know that friendship with the world is enmity of God.  Whoever therefore wants to be a friend of the world makes himself an enemy of God.” 


When you are a friend to the world, and thus a friend of the one who is ruler of the world, the devil, then you make yourself an enemy of God.  It is Satan who is in charge of all that is in the world.  What is the world?

1 John 2.15:  “For all that is in the world — the lust of the flesh, the lust of the eyes, and the pride of life — is not of the Father but is of the world.”


You can look at the world and all that it consists of, and it is Satan who is behind it all.  So if you want to be involved with that, then you are aligning myself and giving allegiance to Satan.  Thus you become an enemy of God.

But if you are a child of God, and positioning yourself as a friend of God, then you are going to abandon all that is in the world.  Satan is going to become your enemy because he is the one behind it all.

The devil is your enemy.  You are not at war with me.  I am not to fight with you.  You may fight against the principles of others.  You may fight against the doctrine of others.  You may fight against the morality of others.  But you are not fighting them.  You are fighting the devil, because he is the enemy.


2.  You Need the Armor of God because the Devil has Wiles

Look at this verse again…

Ephesians 6.11:  “Put on the whole armor of God, that you may be able to stand against the wiles of the devil.”


Not only is the devil your enemy, but you are to stand against the wiles of the devil.  The word “wiles” translates the Greek word “Methodeia.”  It comes from two Greek words.

  • Meta:  “in the middle.”
  • Hordeia:  “Travel or journey.” 

When you put these two words together, you have a word that means, “in the middle of a journey.”  It carries the idea of someone traveling from one place to another, and along the way (in the middle of their journey), there is someone lying in wait to leap out and pounce them.  Because it is something that is premeditated, the word is sometimes translated as “scheme” or “plotting.”

The devil has these schemes.  He plots and plans so that as you are traveling the road of life, he is ever ready to jump out and attack you by deception and trickery.  He wants you to start thinking like he thinks.  He wants his morality to be your morality.  He wants his doctrine to be your doctrine.  All of this is done to draw you away from God and instead follow after him.  Notice how Paul explained it in 2 Corinthians 2.11.

2 Corinthians 2.11:    “lest Satan should take advantage of us; for we are not ignorant of his devices.”


Satan has these devices, these wiles.  But Satan does not operate alone.


3.  You Need the Armor of God because the Devil has an Army

If you keep reading, you are introduced to those who help Satan.

Ephesians 6.12:  “For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places.”

  • “wrestle” means to throw down.  In a wrestling match you try to throw your opponent to the ground and pin him down.  But this is not a word used in the sports arena, but in the flow of the text, it is used as a military term.  It is in reference to a battle, war. 
  • "flesh and blood"   You are standing toe to toe involved in hand to hand combat.  This hand to hand combat is not with a physical enemy.  Who are you against?
  • “against principalities, powers, rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places.  The ones with whom you engage in hand to hand combat are spiritual beings.  They are described as a host of spiritual beings who are wicked and exist in the heavenly places, the spiritual realm. 

You are reading about demons.  Jesus referred to them when He referred to the “devil and his angels”  (Matt. 25.41). 

This is what temptation is all about.  You are tempted by your desires according to James 1.14.  Who puts the object of your desires in front of you?  The demons.

So you are in close combat with demons.  Satan is your enemy.  He dispatches his demons in the unseen realm to place in front you those things that you desire so that you will be tempted and sin.  You have to throw them down, wrestle, by saying “no” to what you want.

Satan is the enemy, and he has a whole army to go against you.  Guess who gets to decide whose side you are on?  You do.  And that is where the armor of God comes into play.



Fighting the Devil with the Armor of God

When you continue reading, you learn about the armor of God, and the Bible gets specific.  You read these verses about the armor of God that helps you stand your ground and throw down the demons who have been dispatched by Satan to defeat you spiritually.  

Notice that there are some things you must possess.  Also notice that there are some things that you must get.  The difference?  When you consider those things that you must possess, it tells you that there are some things that you are to put on and never ever take them off. 


The Armor of God which You Must Possess

Ephesians 6.14:  “Stand your ground, having girded your waist with truth…” 


You are to be honest.  You are to have integrity.  That’s why you can read in Ephesians 4.25, “Therefore, putting away lying, ‘Let each one of you speak truth with his neighbor,’ for we are members of one another.”

You are to pick it up, put it on, and never take it off.  You are to be a person of honesty.

Ephesians 6.14:  “…having put on the breastplate of righteousness”


We are to be right with God and always do the right thing as the Bible defines it.  That’s why you can read in Matthew 5.6, “Blessed are those who hunger and thirst for righteousness, for they shall be filled.”

We are to to pick up the breastplate of righteousness, put it on, and never stop being right with God, never stop doing the right thing.

Ephesians 6.15:  “and having shod your feet with the preparation of the gospel of peace”


It does not say preparation.  It does not say preparation of the gospel.  It says preparation of the gospel of peace.  This is why you read in Romans 5.1, “Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ”

The gospel is a message that is good news.  This good news brings about peace.  This is a message that results in a peace with God and a peace with others. 

You are to be a person who promotes and emphasizes peace and unity between man and God, and between man and man.  It is to be a part of who you are.  It is to be part of your spiritual armor, and you are never to take it off.

When you put on honesty and integrity, always doing the right thing as the Bible defines it, and seeking to be at peace with God and with your fellow man and helping others do the same, that gives you the upper hand when you are fighting against the devil.


The Armor of God which You Must Obtain

There is the armor of God that you must put on and never take it off, but there is also the armor of God that you are to take.

Ephesians 6.16:  “above all, taking the shield of faith with which you will be able to quench all the fiery darts of the wicked one.”


When you are faced with temptation, you are to take up your shield of faith so that you can resist the wiles of the devil.  That’s why you can read in Hebrews 11.6, “But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.”

Ephesians 6.17:  “And take the helmet of salvation…”


You are to view temptation and fight temptation from the viewpoint of someone who is saved.  You are not going to give into temptation.  You are not going to rebel against the God who saved you.  You are not going to betray the One who died for you.  You are not going to jeopardize your relationship with God. 

You are a saved one, and you need to take up those thoughts when you are faced with temptation.

Ephesians 6.17:  “…and the sword of the spirit which is the word of God.”


How did Jesus fight temptation?  In every attempt that you read about in Matthew 4, Jesus replied to the devil with scripture  (Matt. 4.4,7,10).

You fight the devil by using the Bible as one who is saved and wants to stay that way because you believe in God and believe in His Son.

You are to be strong, but this inner strength does not come from your own abilities.  It is your dependence on the power and strength of God and His abilities that gives you the inner strength to fight against the devil. 

God has given you the tools that you need so that you never have to give into temptation.  He has given the life of His Son who came for a specific purpose.  His life was offered on the cross of Calvary.  His blood was shed, so that you and I can stand opposed to Satan and be assured of certain victory.  But you have to choose to be on the Lord’s side
