“A battle manual for every Christian.” —Sinclair B. Ferguson

The Christian life is a battle. We are in a daily struggle against the world, sin, and Satan.

But God didn’t leave us to fend for ourselves. He gave us his own armor—armor that Jesus has already worn on our behalf all the way to the cross. The same power that raised Christ from the dead is now at work inside of us. This book unpacks each of the pieces of spiritual armor Paul describes in Ephesians 6, inviting us to take up the armor each day, all while resting in the finished victory of Christ and the assurance that our strength for the battle comes from him.

“This is another great book of expositions by Iain Duguid. In this unfolding of the armor of God, he shows us not only his well-known exegetical skills and accessible writing style but also his pastoral wisdom. This comes from both years in ministry and acquaintance with spiritual classics.”

- Timothy Keller, Founding Pastor, Redeemer Presbyterian Church, New York City; Chairman and Cofounder, Redeemer City to City

“Here is a rare find! This is the work of an Old Testament scholar with an easy-to-read and engaging style who believes in the ongoing activity of the evil one and writes about spiritual warfare with pastoral wisdom and biblical sanity. He knows that the battle in which we engage and the armor God supplies for us are not ideas dreamed up by the apostle Paul but were deeply embedded in the long narrative of the Old Testament. And he knows that the Lord Jesus himself faced the enemy and field-tested the armor for us. So here is a much-needed book, a battle manual for every Christian to use, and a guide for every pastor to follow.”

- Sinclair B. Ferguson, Chancellor’s Professor of Systematic Theology, Reformed Theological Seminary; Teaching Fellow, Ligonier Ministries

“A typical nightmare for a soldier is being unarmed and undressed on the battlefield. Drawing upon decades of academic and pastoral ministry, Iain Duguid explains why Christ himself is our armor and how, paradoxically, we can only win the battle through the victory he’s already achieved. Along the way, he also opens up wide vistas on how we are to live as battling victors. Highly recommended for personal, family, or group Bible study.”

- Michael Horton, J. Gresham Machen Professor of Systematic Theology and Apologetics, Westminster Seminary California; author, Justification (New Studies in Dogmatics)

“It is a joy to fervently commend this faithful and accessible treatment of Ephesians 6:10–20 by Iain Duguid. It is a powerful, gospel-saturated, Christ-exalting, and disciple-making volume that passionately calls us onward as Christian soldiers, fully dressed in the Christ-secured, Bible-defined, and Holy Spirit-delivered ‘whole armor of God.’”

- Harry L. Reeder III, Senior Pastor, Briarwood Presbyterian Church, Birmingham, Alabama; author, From Embers to a Flame; The Leadership Dynamic; and 3D Leadership

“I like Iain Duguid’s exposition for what he avoids. He doesn’t drive me to futility, nor does he allow me a cop-out. Duguid sees the gospel lurking in everything Scripture demands of us. In each of these expositions, he places us in the hands of our Redeemer. What more could one ask of an author?”
