Put on the whole armor of God, that you may be able to stand against the schemes of the devil. For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places. Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm.
– Ephesians 6:11-13
This call to “put on” the armour reminds us that spiritual readiness is essential to the battle. The Christian life is not one of passive drifting but of active readiness. The church as God’s army must not be naïve about the seriousness of spiritual warfare, nor complacent about the need for divine equipping. When we stand steadfast in the Lord, equipped with His armour, victory over the enemy is a forgone conclusion.
