Paul speaks also in Eph 6:10-17 about spiritual weapons. All the other items – the belt of truth, the breastplate of righteousness, our feet fitted with readiness from the gospel of peace, the shield of faith and the helmet of salvation – are for our protection, to enable us to stand against the devil’s schemes and the things he does to trip us up and cause us to be ineffective in our Christian walk, but the sword of the Spirit is the way we can fight back. Paul makes it very clear this is not a literal sword, when he tells us this sword is the word of God. We’re not battling with natural weapons. (2 Cor 10:3-4)

The word of God is described as a double-edged sword (Heb 4:12) God’s word is living and active and creative. God’s word brought about creation (Gen 1:3; Ps 33:6) and creates new life in us. As we speak the word of God outloud, the enemy is defeated (see Matt 4:1-11). There is power in the word of God which is available to us as we declare the ‘Amen’ of God’s promises in every situation. (2 Cor 1:20).

Let’s be people of the word of God, for this is the way to spiritual victory. (Ps 149:6-9)
