Ephesians 6: Standing Firm When the Battle Is Not Against Flesh and Blood
From the Christian home to the battlefield of the soul, Paul shows us what it means to live faithfully in a world that resists the purposes of God.
Paul has spent five chapters telling the Ephesian Christians who they are in Christ and how they should live.
They have been made alive when they were dead in sin.
They have been brought near to God and united with believers who once seemed like strangers.
They have been called to walk worthy of their calling, to put away the old life, to walk in love, and to be filled with the Spirit.
Now, in the final chapter, Paul brings his letter to its conclusion.
But he does not end with a comfortable assurance that everything will be easy for those who belong to Christ. He speaks of obedience in the home, responsibility in our relationships, and a spiritual conflict that demands the whole armor of God.
The Christian life is a life of grace, but it is not a life without struggle.
Faithfulness Begins at Home
Paul begins with children and parents. Children are to obey their parents in the Lord, and Paul reminds them of the commandment to honor father and mother, the first commandment with a promise: that it may be well with them and that they may live long on the earth.
But Paul does not speak only to children. Fathers are commanded not to provoke their children to anger, but to bring them up in the discipline and instruction of the Lord.
That second command deserves our attention. Authority in the Christian home is not permission to dominate. A father who demands obedience but neglects instruction, encouragement, and love has missed the point. Children are not merely to be controlled; they are to be raised in the knowledge of God.
Paul then addresses servants and masters. His words reflect the household structure of the Roman world, in which slavery was a widespread and deeply unequal institution. He tells servants to serve sincerely, as serving Christ, rather than merely trying to please their earthly masters.
He also commands masters to treat their servants in the same spirit, giving up threats and remembering that they, too, have a Master in heaven, who shows no partiality.
Paul does not tell masters that their social position places them above God's judgment. Both servant and master stand before the same Lord.
The principle reaches beyond the ancient household. Whatever our position in life, our work and our treatment of others belong to our service to Christ. No human authority is absolute, and no human being is beneath God's concern.
Christian faith is not confined to worship on Sunday. It changes the way we live with the people closest to us and the way we treat those over whom we have authority.
The Battle We Cannot See
Then Paul turns to the great struggle that lies behind the Christian life.
“Finally, my brethren, be strong in the Lord, and in the power of his might” (Ephesians 6:10, KJV).
Notice where the strength comes from. Paul does not tell us to become strong in ourselves, to trust our own determination, or to believe that sufficient willpower will carry us through every trial. We are to be strong in the Lord.
That distinction matters. The Christian life demands courage and perseverance, but its resources come from God.
Paul explains why this strength is necessary.
We must put on the whole armor of God so that we can stand against the wiles of the devil. Our struggle, he says, is not ultimately against flesh and blood, but against spiritual wickedness.
We can easily forget this.
We see people who oppose us, institutions that resist us, and circumstances that seem determined to defeat us.
We may begin to think that our real enemies are the people standing in our way.
Paul reminds us that the deepest battle is spiritual. Human beings remain responsible for their actions, but evil is more than a disagreement between people. There is a spiritual adversary who seeks to deceive, discourage, divide, and destroy.
This does not mean that every disappointment is a direct attack by the devil, or that we should stop addressing injustice and wrongdoing in the world. It means that we must recognize the spiritual dimension of our struggle and refuse to fight it with merely human weapons.
Our calling is not to hate our opponents. It is to stand faithfully in the truth of God.
The Whole Armor of God
Paul's picture of spiritual armor would have been familiar to his first readers. Roman soldiers were a common sight, and Paul uses the equipment of a soldier to explain how God prepares His people for the battle.
He names six pieces of armor or equipment, each illustrating a vital part of the Christian life.
The first is the belt of truth. Truth holds everything together. We cannot stand against deception if we are unwilling to believe what God has revealed. Nor can we walk faithfully with Christ while making peace with falsehood.
Next comes the breastplate of righteousness. The righteousness we possess before God rests on what Christ has done for us, not on our claim to be morally superior. Yet the grace that saves us also calls us to live righteously. We are not protected by pretending to be good, but by belonging to Christ and seeking to walk in His ways.
Our feet are to be shod with the preparation of the gospel of peace. There is something striking about this image. A soldier prepares to stand firm, but the message he carries is a gospel of peace. We have peace with God through Christ, and we are called to carry that good news into a troubled world.
Above all, Paul tells us to take the shield of faith, with which we can quench the fiery darts of the wicked one.
Doubt,
accusation,
temptation,
fear, and
discouragement can strike with terrible force.
Faith does not mean that we never experience them. It means that we trust the character and promises of God even when the arrows fly.
Then comes the helmet of salvation. Our minds must be guarded by the assurance that we belong to Christ. The enemy would have us believe that sin has the final word, that failure has placed us beyond God's mercy, or that our future is hopeless. The gospel declares otherwise. Our salvation rests on God's grace and Christ's finished work.
Finally, Paul names the sword of the Spirit, which is the word of God. Here is the one weapon in the list that is explicitly described as a sword. God's Word exposes lies, corrects our thinking, strengthens our faith, and directs our steps.
When Jesus was tempted in the wilderness, He answered Satan with the Scriptures. He did not meet temptation by negotiating with it or trusting His own human resolve. He stood upon the Word of His Father.
We should not imagine that merely repeating Bible verses works like a magical formula. We must know the Word, understand it faithfully, and trust the God who speaks through it.
A Bible left closed cannot shape our thinking. A Bible read without obedience cannot accomplish its intended work in us.
Paul's point is not that we must manufacture our own protection. God provides the armor. Our responsibility is to put it on.
Prayer: The Breath of the Battle
After describing the armor, Paul immediately speaks of prayer.
“Praying always with all prayer and supplication in the Spirit” (Ephesians 6:18, KJV).
Prayer is not another piece of armor to be added to the list. It is the continuing expression of our dependence upon God as we stand in the battle. Paul urges believers to pray at all times, to remain watchful, and to persevere in supplication for all the saints.
Notice how far his concern extends beyond himself. The Christian life is not a solitary struggle in which each person is left to defend his own soul. We are members of one body, and we are to pray for one another.
Paul even asks the Ephesians to pray for him. He is an apostle, a man who has preached the gospel, planted churches, and endured suffering for Christ. Yet he does not regard himself as beyond the need for prayer.
His request is specific. He wants words given to him so that he may open his mouth boldly to make known the mystery of the gospel. He is an ambassador in bonds, and he asks for courage to speak as he ought.
What a remarkable request! Paul does not ask first for the removal of his chains. He asks for boldness to proclaim Christ while he remains in them.
We should not conclude that freedom, deliverance, or relief from suffering is unimportant. But Paul shows us something greater than the desire to escape hardship. He wants to remain faithful to his calling, whatever his circumstances.
The man who has taught the Ephesians about God's power now asks them to pray that he will have the courage to use his own voice.
That is Christian humility. And it is also Christian courage.
A Final Word of Peace and Grace
Paul closes by telling his readers that Tychicus, a beloved brother and faithful minister in the Lord, will bring them news of his circumstances and encourage their hearts.
Even this brief reference reminds us that the early church was not an abstract movement. It was a fellowship of real people who carried messages, visited believers, strengthened one another, and shared the burdens of the gospel. Paul's ministry depended not only on his own faithfulness but also on the service of fellow Christians.
Then come his closing words:
“Peace be to the brethren, and love with faith, from God the Father and the Lord Jesus Christ. Grace be with all them that love our Lord Jesus Christ in sincerity” (Ephesians 6:23–24, KJV).
Peace, love, faith, and grace: these are the words with which Paul concludes a letter that has spoken so plainly about spiritual warfare.
There is no contradiction. The armor of God is not given to make us quarrelsome, fearful, or obsessed with our enemies. It is given so that we may stand firm in Christ, live faithfully, proclaim the gospel of peace, and remain steadfast in love.
We began this letter with God's eternal purpose in Christ. We have seen the riches of His grace, the unity of His church, and the practical demands of a life worthy of our calling. Now Paul leaves us standing in the strength of the Lord, clothed in His armor and sustained by prayer.
The battle is real. The enemy is real. But neither has the final word.
Our confidence is not in the strength of our armor or the courage of our hearts. It is in the Lord who provides both the calling and the strength to fulfill it.
Be strong in the Lord, and in the power of His might.
That is Paul's final charge to the Ephesians. It is a fitting charge for us as well.
****************************
Behold! the Christian warrior stand
In all the armor of his God;
The Spirit’s sword is in his hand;
His feet are with the Gospel shod;
In panoply of truth complete,
Salvation’s helmet on his head;
With righteousness a breastplate meet,
And faith’s broad shield before him spread.
He wrestles not with flesh and blood,
But principalities and powers,
Rulers of darkness, like a flood,
Nigh, and assailing at all hours.
Nor Satan’s fiery darts alone,
Quenched on his shield, at him are hurled;
The traitor in his heart is known,
And the dire friendship of this world.
Undaunted to the field he goes;
Yet vain ere skill and valor there,
Unless, to foil his legion foes,
He takes the trustiest weapon: prayer.
With this omnipotence he moves,
From this the alien armies flee,
Till more than conqueror he proves,
Through Christ, who gives him victory.
Thus, strong in his Redeemer’s strength,
Sin, death, and hell he tramples down;
Fights the good fight, and wins at length,
Through mercy, an immortal crown.
