Devotion for September 15, 2026: Spiritual Warfare and the Armor of God

A concise exposition of Ephesians 6:10–18 from James Boice explaining that Christians fight spiritual forces with God’s own armor — truth, righteousness, the gospel, faith, salvation, and prayer — all found and supplied in Christ.

Useful takeaways from this story.

Paul’s image of the armor of God draws on Isaiah 59: God’s own garments — righteousness and salvation — form the pattern and source.

Each piece of the armor points to Christ: truth, righteousness, the gospel, faith, salvation, and prayer are realities grounded in him.

Focus of this devotion

Boice traces Paul's concept of the armor to Isaiah 59, where God is pictured as putting on armor: "He put on righteousness as a breastplate, and a helmet of salvation on his head" (Isaiah 59:17). That link matters because it reframes the "armor of God" as God's own garments rather than merely equipment God supplies to us.

What each piece of the armor represents

Boice lists the combat needs in Ephesians and identifies Christ as the source of each:

  • Truth (Eph. 6:14): Christ is "the truth" (John 14:6). The truth that sustains believers is God's truth revealed in Scripture and embodied in Jesus.
  • Righteousness (Eph. 6:14): This is not human righteousness but the righteousness of God, given in Christ (1 Corinthians 1:30).
  • The gospel (Eph. 6:15): The gospel is specifically the gospel of Christ.
  • Salvation (Eph. 6:17): Salvation is Christ himself, accomplished by his death on the cross (Acts 4:10–12).
  • Prayer (Eph. 6:18): Prayer functions through the access Christ opened (Hebrews 10:19–20).

Practical implication

Because the forces arrayed against believers are spiritual and powerful, standing against them in personal strength is impossible. The defense available to Christians is union with Christ and reliance on what God himself provides. Appropriating these gifts — truth, righteousness, the gospel, faith, salvation, and prayer — is how believers "put on the whole armor of God" and stand to the end.
