What is the goal of this warfare? To disarm angelic beings? No! Christ has already done that on the cross, as we read in Colossians 2:15: “And having disarmed the powers and authorities, He made a public spectacle of them, triumphing over them by the cross.” It is simply that we take a stand, remain immovable, and that paradoxically is to advance. You advance by standing firm – as Paul repeats in Ephesians 6:11, 13, and 14.
