The short answer
What is the armor of God?
The armor of God is Paul's picture, in Ephesians 6:10-20, of how Christians stand firm against the devil. It has six pieces: the belt of truth, the breastplate of righteousness, feet ready with the gospel of peace, the shield of faith, the helmet of salvation, and the sword of the Spirit, which is the word of God. Then Paul calls for prayer at all times. The armor comes from God, and the goal is to stand.
Read it first
Ephesians 6:10-20
10Finally, be strong in the Lord and in His mighty power. 11Put on the full armor of God, so that you can make your stand against the devil’s schemes. 12For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this world’s darkness, and against the spiritual forces of evil in the heavenly realms. 13Therefore take up the full armor of God, so that when the day of evil comes, you will be able to stand your ground, and having done everything, to stand. 14Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness arrayed, 15and with your feet fitted with the readiness of the gospel of peace. 16In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. 17And take the helmet of salvation and the sword of the Spirit, which is the word of God. 18Pray in the Spirit at all times, with every kind of prayer and petition. To this end, stay alert with all perseverance in your prayers for all the saints. 19Pray also for me, that whenever I open my mouth, words may be given me so that I will boldly make known the mystery of the gospel, 20for which I am an ambassador in chains. Pray that I may proclaim it fearlessly, as I should.

Background
The context of Ephesians 6:10-20
Where the passage sits in Ephesians
Ephesians spends three chapters on what God has done in Christ, then three on how the church should live in response. The armor passage is the last instruction before Paul signs off. Tyndale's study notes sum up the moment: believers "are warned to take on God's armor to protect themselves from the devil (6:10-20)."
Nothing in it is new to the letter. Christ is already seated "far above all rule and authority" (1:21), and Paul uses the same pair of words for the powers in 6:12. The church has been told to "put on the new self" (4:24) and not to give the devil a foothold (4:27). Truth, righteousness, peace, faith and salvation have all come up before. The armor gathers them into one picture.
A prisoner describing a soldier
Paul calls himself "an ambassador in chains" (6:20). Acts 28:16 says that in Rome he lived with a soldier guarding him, and Easton's Bible Dictionary notes he was chained to one. Tyndale's notes say the letter may come from prison in Rome or in Ephesus. Either way, armed soldiers were part of his days, and his readers in the Roman province of Asia knew the gear on sight.
The armor belongs to God first
Paul's list is not only Roman. Several pieces come from Isaiah, where God himself, or the king he promised, wears them. Commentators widely note these echoes. They explain the name: it is "the armor of God" (6:11) because God gives it, and because it is the armor God wears.
He put on righteousness like a breastplate, and the helmet of salvation on His head; He put on garments of vengeance and wrapped Himself in a cloak of zeal.
Isaiah 59:17
Righteousness will be the belt around His hips, and faithfulness the sash around His waist.
Isaiah 11:5
How beautiful on the mountains are the feet of those who bring good news, who proclaim peace, who bring good tidings, who proclaim salvation, who say to Zion, “Your God reigns!”
Isaiah 52:7
Standing, not charging
The verb Paul repeats is "stand". Make your stand (6:11), stand your ground and, having done everything, stand (6:13), stand firm (6:14). Tyndale's notes point out that every item except the short sword is defensive: "There is no picture here of Christians attacking the devil."
The commands are also plural. Paul is writing to a church, so the armor is put on together, by people who pray for each other (6:18).
Ephesians 6:10-20
The armor, piece by piece
Six pieces, each joined to something God gives. Prayer follows, and Paul treats it as the way the whole set is worn.
6:14 · Truth
Belt of truth
A soldier's belt held the rest of his gear in place. Ephesians has already called the gospel "the word of truth" (1:13) and told the church to speak the truth in love (4:15) and to put off falsehood (4:25). Some read the belt as the truth of the gospel, others as a life of honesty. In this letter the two belong together.
Compare Isaiah 11:5. Truth in the Bible dictionary
6:14 · Righteousness
Breastplate of righteousness
The breastplate covered the chest. In Isaiah 59:17 the Lord himself wears righteousness this way. Some read it as the right standing with God that believers receive in Christ, others as upright living. Ephesians 4:24 holds both: the new self is "created to be like God in true righteousness and holiness."
Compare Isaiah 59:17. Righteousness in the Bible dictionary
6:15 · The gospel of peace
Feet ready with the gospel of peace
Good footing is what lets a soldier hold his ground. Isaiah 52:7 praises the feet of those who bring good news and proclaim peace. In Ephesians that peace is first something Christ made: "He Himself is our peace" (2:14), between people and God, and between Jews and Gentiles. Readiness may mean being prepared to share that news, or being steady because of it. Either reading fits the picture of feet planted firmly.
Compare Isaiah 52:7. Gospel in the Bible dictionary
6:16 · Faith
Shield of faith
Smith's Bible Dictionary describes the ordinary shield as wood covered with leather, and notes that in Scripture the shield usually stands for God's protection (Psalm 3:3). Faith here is trust in God, and it puts out "all the flaming arrows of the evil one." Paul does not say what the arrows are. Temptation, accusation and fear are common suggestions.
6:17 · Salvation
Helmet of salvation
The helmet guarded the head, and Isaiah 59:17 supplies this piece too. Ephesians speaks of salvation as already given: "by grace you have been saved" (2:8). In 1 Thessalonians 5:8 Paul calls the helmet "our hope of salvation." Salvation protects as something received and as something still to come.
Compare Isaiah 59:17. Salvation in the Bible dictionary
6:17 · The word of God
Sword of the Spirit
Paul defines the sword himself: it is the word of God, and it belongs to the Spirit. Easton's Bible Dictionary lists Hebrews 4:12 and Revelation 1:16 as other places Scripture uses the picture. When Jesus was tempted he answered each time with Scripture (Matthew 4:1-11), and many readers see the sword at work there. In 6:19-20 Paul asks for words to proclaim the gospel boldly, so speaking the message is part of it too.
6:18-20 · Prayer
Prayer at all times
Paul does not list prayer as a piece of armor. In Greek, verse 18 carries on the sentence that begins with "Stand firm" in verse 14, so most readers take prayer as the way the whole armor is worn. Paul asks for prayer at all times, in the Spirit, for all the saints, and for himself.

Interpretation
Where Christians read it differently
Is the armor what God gives, or how we live?
Some readers take the pieces mainly as gifts: Christ's righteousness counted to the believer, the truth of the gospel, salvation already received. Others take them mainly as a way of life: honesty, upright conduct, steady trust. Ephesians holds both. The armor is God's, and believers are told to put it on. Most commentators keep the two together.
Who are the rulers and authorities?
Most readers take verse 12 as real spiritual beings opposed to God, which is what "spiritual forces of evil in the heavenly realms" says. Some also see those powers at work through human systems and institutions. The passage gives no names, ranks or territories, and a study is wise not to add them.
Is putting on the armor a daily prayer?
Many Christians pray through the pieces each morning, and that can be a good way to remember them. But the passage gives no ritual and no set form of words, and nothing in it suggests the armor works by being named. Paul describes what is true of believers in Christ and calls them to live in it, with prayer that depends on God. Putting on the armor looks like trusting God, telling the truth, living rightly and praying.
Is the Christian life mainly a battle?
Paul gives this picture a few verses at the end of a letter that is mostly about grace, unity and ordinary relationships. Tyndale's notes put it plainly: "Though the devil's opposition is to be taken seriously, Paul's view of the Christian life does not center on spiritual warfare in an aggressive or offensive sense." The passage asks the church to stay alert. It does not ask them to be preoccupied with the devil.

Frequently Asked Questions
What is the armor of God?
It is Paul's picture, in Ephesians 6:10-20, of how Christians stand firm against the devil. Each piece is joined to something God gives: truth, righteousness, the gospel of peace, faith, salvation and the word of God. Several pieces come from Isaiah, where God himself wears them. Paul then calls for prayer at all times.
What are the six pieces of the armor of God?
The belt of truth, the breastplate of righteousness, feet fitted with the readiness of the gospel of peace, the shield of faith, the helmet of salvation, and the sword of the Spirit, which is the word of God (Ephesians 6:14-17). Paul follows them with a call to pray at all times (6:18).
Is prayer part of the armor of God?
Paul does not name prayer as a piece. In Greek, verse 18 carries on the sentence that begins in verse 14, so most readers take prayer as the way the whole armor is worn. Some count it as a seventh piece. Either way, the passage does not end until Paul has asked for prayer.
Is the armor of God only for defense?
Nearly all of it. Tyndale Open Study Notes point out that every item except the short sword is defensive, and that "there is no picture here of Christians attacking the devil." The goal Paul repeats is to stand. The sword is the word of God, which Jesus used against temptation and which Paul asked for boldness to proclaim.
How do you put on the armor of God?
By living in what each piece names: trusting God, holding to the truth, living rightly, staying ready with the gospel, taking in Scripture and praying. Some Christians pray through the pieces each morning as a reminder, which can help. The passage gives no ritual, and the armor does not work by being named.
