Armor of God Bible Study

Ephesians 6:10-18

The armor of God

 Mary Fairchild

The armor of God, described by the apostle Paul in Ephesians 6:10-18, is our spiritual defense against attacks by Satan. Fortunately, we don’t have to leave home every morning wearing a full suit of armor to be protected. Although invisible, the armor of God is real, and when used properly and worn daily, it provides solid protection against the enemy's onslaught.

Key Bible Passage: Ephesians 6:10-18 (NLT)

A final word: Be strong in the Lord and in his mighty power. Put on all of God’s armor so that you will be able to stand firm against all strategies of the devil. For we are not fighting against flesh-and-blood enemies, but against evil rulers and authorities of the unseen world, against mighty powers in this dark world, and against evil spirits in the heavenly places.

Therefore, put on every piece of God’s armor so you will be able to resist the enemy in the time of evil. Then after the battle you will still be standing firm. Stand your ground, putting on the belt of truth and the body armor of God’s righteousness. For shoes, put on the peace that comes from the Good News so that you will be fully prepared. In addition to all of these, hold up the shield of faith to stop the fiery arrows of the devil. Put on salvation as your helmet, and take the sword of the Spirit, which is the word of God. Pray in the Spirit at all times and on every occasion. Stay alert and be persistent in your prayers for all believers everywhere.

In this illustrated, step-by-step study of the armor of God, you'll learn the importance of wearing your spiritual armor daily and how it protects against Satan's attacks. None of these six pieces of armor require power on our part. Jesus Christ has already won our victory through his sacrificial death on the cross. We only have to put on the effective armor he has given us. 

Belt of Truth

The belt of truth is the first element of the armor of God. In the ancient world, a soldier's belt not only kept his armor in place but, if wide enough, protected his kidneys and other vital organs. Just so, the truth protects us. Practically applied, you might say the belt of truth holds up our spiritual pants so that we're not exposed and vulnerable.

Jesus Christ called Satan the father of lies: He [the devil] was a murderer from the beginning. He has always hated the truth, because there is no truth in him. When he lies, it is consistent with his character; for he is a liar and the father of lies" (John 8:44, NLT).

Deception is one of the enemy's oldest tactics. We can see through Satan's lies by holding them against the truth of the Bible. The Bible helps us defeat the lies of materialism, money, power, and pleasure as the most important things in life. Thus, the truth of God's Word shines its light of integrity into our lives and holds together all of our spiritual defenses.

Jesus told us "I am the way and the truth and the life. No one comes to the Father except through me." (John 14:6, NIV)

Breastplate of Righteousness

The breastplate of righteousness guards our heart. A wound to the chest can be fatal. That's why ancient soldiers wore a breastplate covering their heart and lungs.

Our heart is susceptible to the wickedness of this world, but our protection is the righteousness that comes from Jesus Christ. We cannot become righteous through our own good works. When Jesus died on the cross, his righteousness was credited to all who believe in him, through justification.

God sees us as sinless because of what his Son did for us: "For God made Christ, who never sinned, to be the offering for our sin, so that we could be made right with God through Christ" (2 Corinthians 5:21, NLT).

Accept your Christ-given righteousness; Let it cover and protect you. Remember that it can keep your heart strong and pure for God: "Guard your heart above all else, for it determines the course of your life." (Proverbs 4:23, NLT)  

Gospel of Peace

Ephesians 6:15 talks about fitting our feet with the readiness that comes from the gospel of peace. The terrain was rocky in the ancient world, requiring sturdy, protective footwear. On a battlefield or near a fort, the enemy might scatter barbed spikes or sharp stones to slow an army down. In the same way, Satan scatters traps for us as we're trying to spread the gospel.

The gospel of peace is our protection, reminding us that it is by grace that souls are saved. We can sidestep Satan's obstacles when we remember, "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life" (John 3:16, NIV).

Fitting our feet with the readiness of the gospel of peace is described in 1 Peter 3:15 like this: "But in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect" (NIV).

Sharing the gospel of salvation ultimately brings peace between God and men (Romans 5:1).

Shield of Faith

No defensive armor was as important as the shield. It fended off arrows, spears, and swords. Our shield of faith guards us against one of Satan's deadliest weapons: doubt.

Satan shoots doubt at us when God does not act immediately or visibly. But our faith in God's trustworthiness comes from the unassailable truth of the Bible. We know our Father can be counted on.

Faith and doubt don't mix. Our shield of faith sends Satan's flaming arrows of doubt glancing harmlessly to the side. We keep our shield held high, confident in the knowledge that God provides for us, God protects us, and God is faithful to us his children. Our shield holds because of the One our faith is in, Jesus Christ.

Helmet of Salvation

The helmet of salvation protects the head, where all thought and knowledge reside. Jesus Christ said, "If you hold to my teaching, you are really my disciples. Then you will know the truth, and the truth will set you free." (John 8:31-32, NIV)

The truth of salvation through Christ does indeed set us free. We are free from vain searching, free from the meaningless temptations of this world, and free from the condemnation of sin. Those who reject God's plan of salvation battle Satan unprotected and suffer the fatal blow of hell.

First Corinthians 2:16 tells us that believers "have the mind of Christ." Even more interesting, 2 Corinthians 10:5 explains that those who are in Christ have divine power to "demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ." (NIV) The helmet of Salvation to protect our thoughts and minds is a crucial piece of armor. We cannot survive without it.

Sword of the Spirit

The sword of the Spirit is the only offensive weapon in the armor of God with which we can strike against Satan. This weapon represents the Word of God, the Bible: "For the word of God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart." (Hebrews 4:12, NIV)

When Jesus Christ was tempted in the desert by Satan, he countered with the truth of Scripture, setting an example for us to follow: "It is written: ‘Man shall not live on bread alone, but on every word that comes from the mouth of God'" (Matthew 4:4, NIV).

Satan's tactics have not changed, so the sword of the Spirit is still our best defense.

The Power of Prayer

Finally, Paul adds the power of prayer to the armor of God: "And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the Lord's people." (Ephesians 6:18, NIV)

Every smart soldier knows they must keep the lines of communication open to their Commander. God has orders for us, through his Word and the promptings of the Holy Spirit. Satan hates it when we pray. He knows prayer strengthens us and keeps us alert to his deception. Paul cautions us to pray for others as well. With the armor of God and gift of prayer, we can be ready for whatever the enemy throws at us.
