Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. (Ephesians 6:11) 1/ The need of armour. 2/ The key to interpreting the armour in a spiritual way. 3/ The six parts of the armour of God, joined with prayer. **Sermon Summary:** The sermon centers on Ephesians 6:11, calling believers to put on the whole armour of God to stand against the spiritual warfare waged by Satan, who operates through principalities, powers, and the wickedness of this age. It emphasizes that this armour is not self-generated but divinely provided, with each piece—truth, righteousness, the gospel of peace, faith, salvation, and the Word of God—rooted in God's grace and dependent on His strength, not human effort. The preacher underscores that true spiritual defence requires constant reliance on prayer, vigilance, and a life shaped by Scripture, rejecting worldly wisdom and self-reliance. Ultimately, the armour is not a static shield but a dynamic, God-centred posture of faith, where every element points to Christ as the source of victory, and the believer's strength lies not in self but in the living God who empowers through His Word and Spirit.
