Ephesians says to take up “the whole armor of God” to stand against the schemes of the devil and withstand in the evil day. It then lists pieces including truth, righteousness, readiness from the gospel of peace, faith, salvation, and the word of God. See Ephesians 6:11–17.
In Ephesians 6:10–13 the writer closes with a call to draw strength from the Lord rather than from oneself. Believers are told to “put on” God’s full armor so they can keep their ground against the devil’s schemes. These verses begin the concluding charge of the letter, moving from the earlier instructions about daily conduct and relationships into a final, summarizing call for readiness.
These verses frame the Christian life as requiring strength that comes from God, not from personal toughness. The repeated focus is on being “strong in the Lord” and on receiving what God supplies (“the whole armor of God”). That makes dependence and provision explicit textual themes, not just implied ideas.
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Ephesians 6:11-17, then read the surrounding section so the answer stays connected to the passage's flow.
11Put on the whole armor of God, that you may be able to stand against the wiles of the devil.
12For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world`s rulers of the darkness of this age, and against the spiritual hosts of wickedness in the heavenly places.
13Therefore, put on the whole armor of God, that you may be able to withstand in the evil day, and, having done all, to stand.
14Stand therefore, having the utility belt of truth buckled around your waist, and having put on the breastplate of righteousness,
15and having fitted your feet with the preparation of the gospel of peace;
16above all, taking up the shield of faith, with which you will be able to quench all the fiery darts of the evil one.
17Take the helmet of salvation, and the sword of the Spirit, which is the word of God;
