The book of Ephesians ends with a charge to Christians to take up the armor of God so they will be equipped to fight in a spiritually dangerous world. But they often think they must put on this armor themselves in order to stand. In reality, God himself clothes his people with his armor, the same armor that Jesus wore when he won the ultimate battle for us at the cross--and therefore God's own strength is inevitably at work within them. In this reflective book, Iain Duguid walks through Ephesians 6:10-13 from this unique angle, highlighting the Old Testament context of each piece of armor. Readers will be encouraged in their daily battle against sin as they rest in God's power at work in them through the finished victory of Christ.
