Strong in the Lord: Standing Firm in Spiritual Warfare

Paul closes Ephesians by bringing the Christian life into sharp focus: Satan’s crosshairs are fixed on the Christian, so believers must be strong in the Lord. The Christian pilgrimage cannot be approached with a lackadaisical or lukewarm mentality, because the walk from salvation to glory is not a casual stroll across a football field. The path is a battlefield, and the knowledge of buried mines changes everything.

Ephesians 6:10 commands believers to become capable, not by digging down into themselves, but by finding strength in the Lord and in the strength of His might. God’s manifested power and exceptional capability are not merely seen in creation, the Red Sea, Jericho, or the resurrection of Christ. God’s power is presently displayed as ordinary people live extraordinary lives that go against the grain of a fallen world. The life Christ calls His people to live is impossible apart from divine help, yet completely possible through Christ who strengthens them.

Paul then commands believers to put on the full armor of God. God does not recruit soldiers, brief them on the mission, and then fail to give them what they need. God has opened the armory, and He has supplied everything necessary for life and godliness. The issue is not whether the resources are sufficient. The issue is whether believers will take them up and put them on.

Paul identifies the reason for this armor: believers must stand against the schemes of the devil. Satan is a defeated foe, and those who are in Christ are irrevocably secure in Him. Christ intercedes for His people, and no created power can separate them from the love of God in Christ Jesus. Yet Satan remains an active, skilled enemy whose schemes include every sin, false theology, false religion, immoral practice, and worldly enticement.

Paul also corrects the target of Christian conflict. The struggle is not against flesh and blood. Unbelieving neighbors, political opponents, and people caught in sinful ideologies are not the ultimate enemy; they are people who need the gospel’s power to break forth into their deadness. The battle therefore produces prayerful, evangelistic, and compassionate people rather than bitter, reactive, and merely political people.

Paul defines victory with one plain phrase: stand firm. Evil days will come, often as covert and surprise attacks, especially in seasons of idleness, isolation, sorrow, transition, busyness, victory, and nearness to death. The preparation for those days begins today. There is no inactive Christian soldier and no conscientious objector. The pressing question is whether each soldier is prepared to hold the front when Satan seeks to wreak havoc through sin, division, gossip, bitterness, and slander.

Key Takeaways

• 1. Strength must come from the Lord The Christian life cannot be lived through natural grit, religious activity, or a good day of self confidence. Christ calls His people into a life that requires divine power because the calling itself goes against the grain of the fallen world. God’s strength is not abstract; it is His present power at work in ordinary believers who walk faithfully. [48:26]
• 2. God has opened the armory The full armor of God means God has not left His people under equipped for life and godliness. Every command in Ephesians 4, 5, and 6 comes with God supplied resources to obey it. Faithfulness requires more than admiring the armor; it requires taking it up and putting it on. [53:57]
• 3. The devil schemes, but cannot own believers Satan’s schemes are serious, but they are not ultimate. Those in Christ are irrevocably secure because Christ died, rose, reigns, and intercedes for them. Satan can seek to steal joy, cloud witness, and create havoc, but he cannot sever Christ’s people from Christ’s love. [62:35]
• 4. People are not the ultimate enemy The struggle against spiritual wickedness changes the tone Christians bring to a hostile world. People who oppose the gospel are not targets for contempt, because the gospel once found every Christian blinded, trapped, and dead in sin. Prayer, clear gospel proclamation, and patience fit the battle better than political rage or personal bitterness. [66:53]
• 5. Preparation begins before evil days arrive Evil days do not announce themselves before they come. Spiritual readiness is formed in the ordinary days through watchfulness, obedience, and refusing lukewarmness. A soldier who waits until the battlefield to prepare has already misunderstood the battle.

Bible Reading

Ephesians 6:10-13
“Finally, be strong in the Lord and in the strength of his might. Put on the whole armor of God, that you may be able to stand against the schemes of the devil. For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places. Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm.” [18:00]

Romans 8:33-39
“Who shall bring any charge against God's elect? It is God who justifies. Who is to condemn? Christ Jesus is the one who died—more than that, who was raised—who is at the right hand of God, who indeed is interceding for us. Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or danger, or sword? As it is written, 'For your sake we are being killed all the day long; we are regarded as sheep to be slaughtered.' No, in all these things we are more than conquerors through him who loved us. For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord.” [01:00:30]

2 Corinthians 4:4
“In their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God.” [01:07:29]

Observation questions

1. In Ephesians 6:10–13, what repeated actions are believers commanded to take, and what outcome are they meant to produce? [01:10:18]
2. What does Paul identify as the source of a believer’s strength, and how is that different from relying on personal ability or resolve? [48:24]
3. According to Ephesians 6:11–12, who or what is the true enemy in the Christian’s struggle, and who is specifically not the ultimate enemy? [01:04:17]
4. What kinds of schemes and attacks were identified as ways the devil seeks to harm believers and churches? [01:06:21]

Interpretation questions

1. Why does Paul place the command to be strong in the Lord after his instructions about living faithfully in marriage, family, work, and the church? What does this suggest about the opposition believers may face when they pursue obedience? [46:39]
2. If Satan is defeated and believers are secure in Christ, why does Paul still speak with such urgency about standing against the devil’s schemes? [01:03:09]
3. How does the truth that the struggle is not against flesh and blood reshape a Christian’s response to people who promote sinful ideas, oppose the gospel, or cause personal hurt? [01:08:00]
4. Paul describes victory as standing firm rather than accomplishing something dramatic. What might “standing firm” look like in an ordinary believer’s life during an evil day? [01:10:35]

Application questions

1. Where is there a temptation to approach the Christian life casually, half-heartedly, or mainly through self-confidence? What would it look like to become strong in the Lord in that specific area? [53:00]
2. God has supplied everything needed for life and godliness, but believers must take it up and put it on. What spiritual resources has God already provided that may be admired or known about without being actively used?
3. Consider the seasons when attacks often come: idleness, isolation, sorrow, transition, busyness, after a victory, or nearing death. Which of these seasons is most relevant right now, and what wise preparation could begin this week? [01:15:23]
4. Is there a person, political group, neighbor, coworker, or family member who has become an enemy in the heart rather than someone in need of the gospel? How could prayer, compassion, and clear gospel witness change the way that relationship is approached? [01:08:41]
5. Satan seeks to steal joy and damage witness through sin, bitterness, gossip, slander, and division. Is there any conversation, conflict, or attitude that needs to be addressed before it gains a foothold? [01:20:03]
6. Every Christian is already in the battle; the question is whether each believer is prepared. What one regular practice—such as Scripture, prayer, confession, fellowship, or encouraging another believer—would help build readiness before a difficult day arrives? [01:16:55]
