Which verse calls believers to put on the full armor of God to stand against the devil's schemes?

• A. Romans 8:37
• B. Ephesians 6:10
• C. 2 Timothy 3:16
• D. Isaiah 59:17

Answer: (B)

Believers win spiritual battles by relying on God’s strength and wearing the armor He provides. The command to “put on the full armor of God” is part of the Ephesian letter’s section on spiritual warfare; it follows the exhortation to be strong in the Lord and stands as the practical application of that call. The point is not to rely on human power but to stand firm by God’s resources, prepared for the schemes of the devil.

The armor imagery then unfolds: truth as a belt fastening everything together, righteousness as a protective breastplate, readiness of the gospel of peace on the feet, the shield of faith to extinguish fiery darts, the helmet of salvation, and the sword of the Spirit, which is God’s word. Prayer is highlighted as essential to staying alert and persevering in the struggle. The surrounding context makes clear that this is about resisting spiritual opposition, not merely facing ordinary challenges.

So, the concept tested hinges on recognizing that true defense and victory come from God’s provision of armor to stand against Satan’s schemes, with the Ephesian passage providing the direct exhortation and the details of what that armor entails. The other verses touch on related ideas—strength in the Lord, Scripture for teaching, or imagery of armor elsewhere—but the one that most directly ties the command to don the armor against devilish schemes is the Ephesian passage in its surrounding context.
